Grid card - comment

Configuration Frontend

Hi. Still fairly new to HA but I managed to create a dashboard that I really like. I need to tweak it a bit and there is my problem. I’m editing a grid card with a xiaomi-vacuum-map-card. See right bottom on the screenshot.

I want to delete the room names, but I need to remember which code is relating to which room. Therefore I want to add comments in the visual editor with the #. But the comments are not saved.
Am I doing something wrong?

Storage mode does not support comments as it is stored as json and converted to yaml for editing, and json does not support comments.

Only YAML mode supports comments.
