Paginated Reports - Dropped Parameters

Hello!

I have a paginated report uploaded to a premium Power BI workspace, which has only one parameter (single value parameter). Recently, I ran into this error below despite not changing anything on the report. After receiving the error, I noticed the section highlighted in SCREENSHOT #2 below disappeared from the subscription, but showed back up a few hours later without any changes on my end. Has anyone run into this issue before?

Thanks!
