Something isn’t being saved properly in the Inspector pane. If you change the space allowed for meta-data and the keywords (see image below), it works fine while you have that project open - turning the Inspector pane on/off doesn’t make a change to the spacing layout.
However, if you then save and close the project, then reopen it or any other project, the layout goes back to the default as shown in this image:
This has been the norm for quite some time and not mentioned elsewhere.
