I'm attempting to format the legend in a map, and for most of the legend items, I can simply type in a new pt size or use the arrows to increase the patch width and height. For some reason, two of the layers seem to be locked in their patch size. When I attempt to change the numbers they just bounce back to [24pt Patch width] and [24pt Patch height] every time. I tried selecting the features out of the layer and creating new (separate) layers and that didn't solve anything. I of course also tried closing and restarting, turning layers on/off etc.
I resolved the issue. The polygon layer that was locked/non-modifiable was symbolized into two 'unique values,' so I ended up breaking up the layer into two separate layers and then re-symbolizing each of them as 'single symbol,' and somehow that gave me control again. Seems like it was just a weird glitch to me.
