Solr stats updating for some items and NOT all

[gustav chinovava]

Dear DSpace Community

I am on DSpace 7.6.1 and bumped into a challenge with solr stats for items displayed in the web UI.

I can see all stats imported from DSpace 6.3 but April stats are updating for some items and NOT all.

When I check both dspace.log and solr.log by item uuid, I see both item interactions logged successfully.

Anyone to point me in the right direction on how to troubleshoot this further?

Regards
