I think Adjustment Layers are a last resort for a session. My advice would be to not use them unless you had some specific overall thing you needed to apply in addition to what was already done in the Color page.
Note you can always do the equivalent of an adjustment-layer correction as a Timeline Grade, and you can also keyframe it if necessary. I do this all the time to add a letterbox or positional change for an entire feature, while leaving bars, slates, countdown and so on unaffected.
If you want to troubleshoot this, you could check under Edit History and see if the Adjustment Layer changes are listed there. If they're not, then you can't Undo them. If they ARE listed, then they should be just as Undoable as any Edit change.
