Crazy Problem - Move timeline (many seconds) when double-click on Pre-Comp to open it !!!

[Ousama AlRefai]

Hi, My Friends.

I have a crazy problem with After Effects.

I Have a Main Composition called (Full-Comp) and Sub-Comp called (Scene1) in the main one (Full-comp).

When I double-click on (Scene1) to open it in Timeline, the comp (Scene1) opens originally, but when I Go back to the main Comp (Full-Comp), the problem is that [[(Timeline Cursor) moves many seconds forward (11 seconds and 35 Frames)]]!!!

[Look at 2 images I attach]

And again when I repeat double-click on the same comp and go back again, the timeline cursor goes forward 11 seconds and 35 frames !!! ... etc !!!

This problem happens just with this comp. I mean this problem doesn't happen with other comps.

Can you help me, please?

What's wrong ??

Hi @Ousama AlRefai,

This sounds like the result of the Synchornize Time of All Related Items preference, which is on by default. You can disable it in Preferences > General.

More detail on the preference can be found here: https://helpx.adobe.com/after-effects/using/precomposing-nesting-pre-rendering.html#WS725e431141e7ba...

I have moved your post from the Bugs category to the Discussions category. If you think that this preference is not contributing to your issue, we can continue to investigate and move it back if necessary.

Thank you @TimKurkoski 
But this solution prevents me from synchronizing when using (New Viewer) and two composition panels!

And also I said in the post that this problem happens just with this sub-comp. In other sub-comps, there is no problem, (no moving after double-clicking) and (synchronizing between the main and sub-comps well).

Apologies, I missed the comment that this was comp-specific.

Mylenium has responded below, I think he may be on the right track RE: time remapping, which can affect the relative time that After Effects uses with the "Synchronize Time" preference.

If that's not it, the most helpful thing you could do is post the project file so we could try it ourselves.

You have a duplicate time-remapped instance of the same pre-comp below and AE will reference the timing of that.

I didn't use time-remapping.

[Mylenium]

You surely did! It says so on your own screenshots for layer 47.

Thanks very much, @Mylenium.

OK, The problem was solved when I deleted time remapping then deleted layer 47 (and then Ctrl+Z, Ctrl+Z) !!!!!

But sorry, I don't understand anything !!!
What's the problem? what happens? why did that happen and why did the problem didn't occur again when I pressed Ctrl+Z ?!!!!

Can you explain to me??

Thanks.

[Ousama AlRefai]

I was using Time remapping in (Layer 47), not in the same layer (46), and even though the problem was solved after deleting (layer 47) !!

I don't understand, what's wrong!!
