Here's a new way to waste time:
Turn on another raster to do something with and Pro decides to style the top raster to a previous style.
No amount of refresh will show the correct symbology until you turn off the other raster.
just wanted to run a quick profile.
If you dare try to edit / fix the style it mess up the label text, likely break the function chain.
Just quietly turn off the bottom raster, open a new Pro instance and do whatever you wanted to do there.
