Strange glitches with Advanced Layers?

Hey there!

I'm encountering some strange errors when rendering out files that have Advanced Layers active. Trouble is, I can't easily replicate the issue as it doesn't seem to happen all the time.

Frame 1 tweaks - Sometimes, when rendering a file that contains advanced layers, frame 1 of the render will have some symbols in a completely different location and sometimes scale. The file seems completely fine and it only seems to show up when it renders out in a .mov.  I figured the Advanced Layers are the issue when I discovered that disabling the Advanced Layers of the document lead to proper rendering. Or, if I push the entire scene to start on frame 2, instead of 1, and render out a blank frame on 1, then everything works fine.

Incorrect Graphic Symbol Display - Usually disabling the Advanced Layers helps, however, in scenes where I need to use the attributes of an Advanced Layer, I can't really disable them and call it a day. I recently ran into an issue with them where a symbol, using advanced layers, would end up glitching at various different points along a tween. I was just animating pupils tracking another character and the pupils had a simple bevel filter on them to fit the design. Since the pupils were traveling in an arc, I did some quick classic tweens and when render time came around, a frame before a new tween would take over, the pupils would pop back to the initial position of the tween.

Is there something I'm doing wrong? Is there a step that I'm missing or some property I don't know about that needs to be active to prevent this. I can't really share the file or screenshots of the issue, as it's part of a project, so all I really have is words to describe what's going on.
