When you have created a complex manual interval with custom label entries symbology and you change one interval value, Pro resets every label back to defaults and not just the changed interval.
Simple example
Custom symbology:
![RTPL_AU_0-1721780073370.png RTPL_AU_0-1721780073370.png](https://community.esri.com/t5/image/serverpage/image-id/110434i96F185AC0A202DFC/image-size/medium?v=v2&px=400)
Dare to change one value:
![RTPL_AU_1-1721780110794.png RTPL_AU_1-1721780110794.png](https://community.esri.com/t5/image/serverpage/image-id/110435iA75862665FAD23EA/image-size/medium?v=v2&px=400)
Now I have to redo all the legend labels.
