@ari I’ve just downloaded and used the Manga Style speech bubble vector libraries by @kaichi1342 as described in this topic:
Manga Style Speech Bubble V2.0 - Vector Library
I had no problem with showing and manipulating (but you have to Ungroup them) the vector shape properties when using the Dec 16 5.1.0-prealpha.
I could also group them and ungroup them.
Can you explain in more detail what was going wrong for you?
Maybe in a separate topic?
