There seems to be a bug when I try to add both the sub-menu and the parent-menu in Groups > Access Permissions > Access Menu
For example, adding both Inventory & Stock and Inventory & Stock / Locations will result in Locations disappearing from the menu for all other users not under this group. (Test group not affected)
Immediately after saving,
Inventory & Stock / Locations disappears
Upon refreshing
I will not be able to find Inventory & Stock / Locations from the Access Menu list as well.
Deleting the Test group would “release” Locations and resolve this issue
