Error with Column Name with special characters

I'm having a problem creating charts or filters where words have accents.

This chart is using the month (in Portuguese is "mês"), when I create the chart works well, when I close and reopen the file in some charts gives me error, does not recognize the name:

The chart does not recognize the word with accent. This happens in the slicers or filters applied to the visual or the page. The strangest thing is that it doesn't happen with all the visuals.

I have the latest version installed, I have already uninstalled and reinstalled, I have already repaired.

This only happened a few days ago, probably with the July version.

When I publish the report the errors remain.

Thanks
