This references to the issue describes here and I found out it applies to any command selections
Open IDE in side bar
From there open IDE in window
Insert a new line in the code “Empty” Line [Insert new Line]
In Command type “Pause” and DO NOT ENTER
Click into the “Target” or “Value” Field
→ Command blanks out
And I also confirm that this was working with version 8.3.9 not not with the new version that supports side bar.
