Problem with adding a Season Pass / Keep 1

From the Web Admin UI, while in the guide, I choose a show to record and select new season pass. For the keep option, I choose "last one only". With these options the the system just keeps spinning and does not create the pass.

The log shows this error:

2020/09/16 21:18:02.294856 json: cannot unmarshal string into Go struct field Rule.KeepNum of type int

If I choose All for the keep option it creates the season pass.
