Advanced Segments not working after 5.4.1

I have the Advanced Segments addon. After updating Jetpack CRM to 5.4.1, some of my segments which have conditions based on custom fields no longer work.
In the segments list, they have a red warning icon.
When I try to edit the segments that use custom fields and have the warning icon, I see this message:
“Segment Warning
There is an issue with this segment:
This segment was created using custom conditions (e.g. from the Advanced Segment extension), and it appears that those conditions have been removed. Please reactivate any related extensions or functionality, or remove the custom conditions this segment.”

Other segments which use Status as a condition cannot be saved. When I try to save a segment with a Sttus condition I get a popup saying “General Error #219 There was a general error”.
