Summary: Realms Plus catalog doesn't show the correct pack counts

Affects currently Live Content: Yes - but store UI only, not our content.

Impact: Realms Plus catalog doesn't show the correct pack counts. Clicking on each pack type changes the quantity.

Repro Steps:

1. Open the Marketplace.

2. Click your profile name at the top.

3. If its the first time you've opened the UI, the counters in the "owned" section are all likely very large negative numbers (in their thousands - they look like unsigned integers) for a brief moment.

4. Expand the "Current" section of the Realms Plus section on the sidebar. Then click on "All", "Skins", "Worlds", etc. You will notice all of the counts change after clicking each type, and in most cases do not actually match the number of results returned by the store. E.g. if you select "All" you will see 44 worlds, but click "Worlds" and the count changes to 70... however, you will notice that the store listing itself reports 77 items.

Observed Results: The product counts in the Realms Plus catalog are wrong.

Expected Results: The product counts in the Realms Plus catalog should be correct.

Screenshots/Videos attached: Yes (see attached video)
