I am making a map with two main maps and a single inset map for context. My scalebar appears to be showing the correct scale for the inset map, but when I add a scalebar to one of the main maps it is wrong. The project CRS is NAD 83/UTM 11N so the issue shouldn't be anything with degrees like other people have noted.
As you can see in the image, the lower selected scalebar is very similar to the upper inset map scalebar, when it should be showing 100s of meters rather than 1000s of kilometers. On the far right of the image you can see the selected scalebar is supposed to be associated with map 3 (which is correct) but just in case I tried changing the map setting to each of the three maps but nothing changed.
How do I get a correct scalebar on multiple maps in a single map layout in QGIS?
