GROUP_CUSTOM_TITLE was added back in 7.1 and we used it for a few versions. We dropped it in 7.3.2 at the tail end of that altertable script. If you're still stuck on this you can manually add that field back in and then the altertable will run properly and drop it at the end. You can do that with this query:
alter table ubbt_GROUPS
add GROUP_CUSTOM_TITLE tinyint(1)
