Hi, I have the same issue. Using different Jira filters as sources, different custom fields are offered to be synched. And I couldn't spot any rule or pattern based on what criteria, airtable is doing that. Any help will be really appreciated.

Hello. I just ran into this problem as well, and luckily I've just recently redone our entire Jira schemes and was able to easily debug the issue for this. It appears that Airtable is looking at the Create screen for picking up these fields to sync. If your custom field is not present on that screen, it will likely not show up as a field to sync into Airtable.

I tested the intregration feature when it got released and could not figure out why so few fields were getting synced (8 exactly), some of which even remaining empty. Now months after I see no progress and am also at a loss when it comes to understanding which fields actually get synced... Is the feature of value to anyone?!?
