I have some data with numbers between 1 and 47. I want to use proportional circles to show the sizes, and if you look at the circles, they do seem to be showing the data correctly. However the auto generated legend only goes up to 10. Also, if I choose to show more than 5 levels in the legend it doesn't do it, but will do it if I try to show 4 or less though still maxing out at a value of 10. If I choose graduated levels, it correctly recognises that the max value is 47, so I don'y know why it is having issues with the proportional symbols.
Attached is a picture of the symbols and legend, as well as the attribute table field being shown.
There is no normalization.
Units are "Unknown unit"
