JTST Environment: Sorting by Contributors or Publisher Columns Give Different Result Counts Than Sort by Title or No Sort

Steps to repro:

1. Log into https://jtst.int.aws.folio.org/ which has the Goldenrod version of RMB and MODINVSTOR
2. Go to inventory
3. Conduct a search, for example:
   1. Filter Language = English OR
   2. Query search source==marc OR
   3. Keyword search: English
4. Hit enter key or search button to execute search
5. Click the Title column to sort by title if it isn't already and observe result count number
6. In the URL, remove the &sort=title and observe the result count (should be the same as sort by title)
7. Now click the Contributors or Publishers columns and observe the result count

Expected: Result count should be the same whether I am sorting by Title, Contributor, Publisher or no sort at all

Actual: Result counts for sort by title and no sort are the same while the sort by contributor and publisher are different (though they match one another)
