ArcGIS Pro - Susceptibility Map Displaying 4 Classes (2-5) Instead of 5 (1-5)

Hello everyone,

I'm working on a susceptibility mapping project in ArcGIS Pro, and I'm running into an issue with my final output map.

My susceptibility scale ranges from 1 to 5, meaning I should have five distinct classes represented (1, 2, 3, 4, 5). However, no matter what I try, my final map is only displaying four classes: 2, 3, 4, and 5. Class 1 seems to be entirely missing from the symbology and the map itself.

I've checked my raw data and the susceptibility raster, and I can confirm that values of '1' are present within the dataset.

Has anyone encountered this before?

Worth checking that there aren't inconsistencies with symbology (do you have All other values turned on) and that there are no definition queries. Beyond these tips, I can only recommend sharing more (e.g. screenshots or a package) so that we can make better guesses on where the issue might lie.
