When >20 sets, the degree aggregation stop working and the query always return the full set

Hi dear community.
I have a data with 41 sets and 1202 rows. I set up a local version of UpSet and tested it with the data. I noticed that once when I include 21 sets, UpSet behaved strangely.

When only 20 sets were included, everything was fine:

Then just added one set, any set, the degree aggregation disappeared, only Degree 21 was showing:

Under such a circumstance, the "click-query" also stopped working, so if I clicked on the fifth row "8", the "Element Queries" erroneously showed "1202" instead of my selected 8.

I did find that if I clicked the "edit" pencil under "Query Filters" and just confirmed it by the "check" symbol, it did show my 8 then:

Thanks!
