Purple bits appear when I render using blender render

Question

I am trying to make a doughnut from a tutorial but apparently there's some extra purple bits on the bottom of the donut when using Blender Render:

This is what I want:

the donut have a subsurface rad of 0.1, 0.1, 0.1 and the color of bread with subsurface color of lighter bread, the icing have a subsurface rad of 0.3, 0,1, 0.1 and pink color and subsurf is pinkish-red color. the plane has a color of pink.

my version is 2.81

and here is my collection

@susu the donut have a subsurface rad of 0.1, 0.1, 0.1 and the color of bread with subsurface color of lighter bread, the icing have a subsurface rad of 0.3, 0,1, 0.1 and pink color and subsurf is pinkish-red color. the plane has a color of pink. — new Q Open Wid, Jan 24 '21 at 18:01
Have you made a backup/archive? There might be 2 donuts rendered overlapping — Blunder, Jan 24 '21 at 18:02
@Blunder Yes, but I turned off the visibility for the archive. — new Q Open Wid, Jan 24 '21 at 18:03
Yes, please add a screenshot of the blender window and the blender version that you use. To me it looks loke you have 2 donuts and 2 icings rendered. The "eye" icon is just for viewport visibility. — Blunder, Jan 24 '21 at 18:07
@Blunder then how do I do it for blender render visibility? also my version is 2.81 — new Q Open Wid, Jan 24 '21 at 18:11

The problem is that a backup copy of your donut and icing are still rendered. The image displays 2 versions of the donut+icing.

To fix this in Blender 2.8x: Like mentioned by susu in the comment, you need to display the "camera" icon in the filter settings first. Then you can enable/disable the rendering of objects or whole collections in the outline: Avoid rendering hidden objects (blender 2.8)

In Blender 2.9x the collections have a checkbox. If you uncheck it, then it automatically disables visibility in viewport and rendering.
