Problems with visualizations following Browser Refresh

I have a Power BI report that I have written in Desktop. Relevant visuals pictured here.

Those numbers are correct.  When I publish it to the service, before I connect it through the gateway, the data remain correct (Service version on the far left, local Desktop version on the far right).

When I connect it to the gateway and refresh the semantic model, the data remains correct (Service version on the far left, local Desktop version on the far right).

However, if I refresh the browser (Google Chrome), or navigate away from PBI Service and then back, I get the following (Service version on the far left, local Desktop version on the far right).

I did not click anything, I did not apply any new filters. I did not interact with the report in any way other than opening it.  Why is it suddenly different, and how do I fix it?

I have cleared the browser cache. I did not work. I have refreshed the published report again. I didn't work. I have refreshed the Desktop report to confirm what I think to be the correct numbers are correct. They are.  They only thing I have found that fixes this issue is deleting the semantic model from PBI Service, and republishing.  Even then it only stays correct until I navigate away from the page, and then it is back to the last image above.
