UCD90120A: Fusion Digital Power Designer crashes whenever I remove a GPI (offline)

I am attempting to modify an existing Fusion Digital Power Designer project (device is the UCD90120). The device is not connected, so I'm in offline mode. 

Everything seems to work fine except that every time I remove a GPI, there is a Fatal Program Error and the GUI crashes. This happens even if I add a new GPI and immediately delete it. I can delete GPOs without any issue. Any idea how to avoid this problem?


Thanks in advance
