@congchen1101 thank you for your contribution. Anyway, I've checked on the same map you indicated in the connected issue but I'm not reproducing the problem. All seems working as expected. Are there maybe other preconditions to respect to reproduce the problem?

Hi @tdipisa,
thanks for checking. Please make sure the selected layer already has a description, but that this description does not come from the corresponding GeoServer abstract field. Then switch to the Style tab and back to General—you should see the issue.

The video I shared was recorded today, and I have just checked again — the bug is still present when performing the exact steps on the layer poly_landmarks. There are no other preconditions and this layer should meet all the required conditions.
