[BUG] Something goes wrong with item / shape edition

[AurelSM]

Hello,
Here i try to edit an item not realised from Item Editor. Which come from Nadeo Importer / Convert Assistant.
As you certainly know, we have access to shape properties etc...

I have issues with shapes.
You have to edit an item > try to change / delete shape etc... That issue is a bit random to generate
And you can notice that it will also affected another independant item.

Here the video (french only, sorry)>
