Hi.
I think I may be observing a bug/regression in Synfire v2.5.5 build #1 (on Windows 11).
Playing back these 4 snippets (by successively clicking the arrowhead on each one):
gives the following result in the Structure view after choosing 'Make Arrangement from Last Session':
As can be seen, the containers all were named according to the Snippet Group, rather than according to the individual snippet names.
In case it is relevant, these particular snippets were complex snippets.
