I am having trouble finding a custom attribute in the attribute search when creating a segment. I have already checked the tracking issue (as described here: https://www.rainforss.me/articles/cannot-find-a-table-when-trying-to-add-new-tables-to-segment) but the contact table is already tracked by default. The tracking is also allowed on the attribute itself. Any ideas why the contact attribute is not showing up in the search when trying to build a segment? Thanks!
