• Tracker>Main>DIsplaying Rules.
• Unmark "In Raid"
• Switch to another tab and back
• See only "Display in combat" is unmarked (even if it was marked), other lines are marked and placed in different order

It's a bug. The options aren't linked to right setting : editing 'Display in Group' will modify the value of 'Display in Combat'.

I believe he hasn't implemented it yet.

Change it to macro conditionals and use the following code:

[combat][group:party][group:raid] hide; show

it'll cause it to be hidden in combat and in raid and party groups.
