Unwanted vertical whitespace after 'tasks' environments

Question

I'm using the tasks package to build a set of math tests. Some of the problems need to be in one column, and some of them need to be in multiple columns, so I'm using separate tasks environments. However, every time I end one tasks environment and start a new one, I end up with some extra vertical whitespace that I don't want. Case in point:

\documentclass{article}
\usepackage{tasks}

\NewTasks[
counter-format={tsk[1].}, 
label-format=\bfseries,
label-width=0.25in,
label-align=right,
label-offset=0.1in,
item-indent=0.35in, 
after-item-skip=10pt, 
resume=true
]{problems}[\prob]

\begin{document}
  \begin{problems}
    \prob Single-column problem 1
    \prob Problem 2
  \end{problems}
  \begin{problems}(2)
    \prob Double-column problems
    \prob Problem 4
  \end{problems}
\end{document}

Where is this whitespace coming from? And what's the best way to get rid of it? Should I set after-skip to a negative value? How much? I'm using ShareLaTeX, by the way, if that makes a difference.

Not all but the minimal ones so we can copy and paste your code to test it. — Sigur, Jan 13 '15 at 18:14
There is an extra 6pt plus 2pt minus 4pt between the lists (seen via using \showoutput), which you can remove by inserting \vspace{-6pt plus 4pt minus 2pt} between the lists. But perhaps there's a better, automated way of doing this. — Werner, Jan 13 '15 at 19:02
You can use a single problems environment with two-column layout and use \prob! for items spanning both columns, as in: \begin{problems}(2) \prob! Single-column problem 1 \prob! Problem 2 \prob Double-column problems \prob Problem 4 \end{problems} — Gonzalo Medina, Jan 13 '15 at 19:07
@JosephMontanaro: Add it to your document (wherever) and check the .log file. It will include all the pages that are shipped out from wherever you place \showoutput in a nested/boxed fashion. You can interpret the \glue that is inserted, the characters and from which font... all nifty, garbled stuff. — Werner, Jan 13 '15 at 19:54
Without a working MWE, I think you should try after-skip = -\parskip , % undo paragraph skip) as suggested in this answer: http://tex.stackexchange.com/a/208060/43189 — alwaysask, Jan 14 '15 at 06:48

This is no longer a problem in the up to date version of tasks:

\documentclass{article}
\usepackage{tasks}[2022-01-08]
\NewTasksEnvironment[
  label = \arabic*. , 
  label-format = \bfseries ,
  label-width = 0.25in ,
  label-align = right ,
  label-offset = 0.1in ,
  item-indent = 0.35in , 
  after-item-skip = \topsep, 
  resume=true
]{problems}[\prob]
\begin{document}
\begin{problems}
  \prob Single-column problem 1
  \prob Problem 2
\end{problems}
\begin{problems}(2)
  \prob Double-column problems
  \prob Problem 4
\end{problems}
Or:
\begin{problems}(2)
  \prob* Single-column problem 1
  \prob* Problem 2
  \prob Double-column problems
  \prob Problem 4
\end{problems}
\end{document}
