ungroup frames then drawing dissapears

i have a group of frames/drawings but when i ungroup them to see their contents (dont know if theres another method)then another drawing thats not part of the group dissapears or it only shows the content of the ungrouped group but anything thing not in that group disapears(ㆆ_ㆆ)

There’s not enough info provided.

You can expan a group in the timeline or if you have the Pro version - from the network. Most likely there is a Peg dependancy in your network (I mean a network of element connections) that you have disrupted by the ungroupling somehow.

If you’re really stuck contact support to have a look.
