I have tried it to check in the display options but their i havnt found any button like "Rebuild global list"
It should work i guess check the capability for the operator or else in the button conditon put the condition as "true" because i dont think gl access would be available to any user's in your environment so it will be harmless removing the condition
In my case, the problem was solved by removing the "AlwaysAdmin" capability.
This capabilty will make the globallists displayed using the db.view display instead of the global.view one.
The "global.view_rebuildlist" display option is related to the "global.view" screen ID, not db.view
