Scorecard returning incorrect calculations

When looking at a month to month comparison of May vs April, the Comparison calculation shows a negative when in GA4 it shows a positive. When I manually go back to the June vs May comparison, the Comparison calculation is different from what it originally was. When I refresh my browser, the Comparison calculation for June vs May goes back to the correct calculation.

I connected to the GA4 account. I've verified the Primary field Metric is correct. There are no filters.

This is not happening to any of our other client's reports, that I'm aware of. I've only viewed a handful so far.
