Is this supposed to happen? I used the auto-completion menu and selected a valid value it shows (first one from the menu), then Mathematica complained that the choice selected is not valid !
ClearAll[x];
Solve[Tan[x] == 1, x, MaxExtraConditions -> None]


Should not all choices shown be valid for the command they show up for?
Solveinternals and it is no longer. Either way, seems buggy to me. – b3m2a1 Aug 19 '17 at 05:15
