Out of Band Cumulative Updates Question (opens in new tab)

I installed March 2026 Cumulative Update on a new server instead of April due to some RC4 changes to test something. I noticed that after the update installed in the event viewer it thinks the June 2026 update was installed. I don't see the June update under installed updates but shows up in update history. The build version of the server matches with the March 2026 update. Is this a weird side effect of installing a superceded update? I'm having trouble understanding what is going on.
