Hello,
I am having an issue with the BPMN pool node which is grouped with other symbols. Somehow it got shrunk. I do not know what I did, but I cant get it in the initial state anymore. Please also not the Overview on my screenshots. In some views the lower graphs disappeared.
So here is the initial view:

This is what I am looking at now:

This is what happens if I resize this BPMN pool node:

If I double click the node, this happens: (the other elements are still there)

So has anyone an idea what happend and how I could reverse this? Ctrl+Z does not work anymore because I closed the document)
Thanks!
Edit: I just saw, that the images are too big to be displayed. It works if you open them in a new tab.
