button-card: Bug after adding the card to lovelace new storage mode

Hi there, first of all thanks for that hard work on this! Whenever i add this card to the UI i cant use the raw config editor anymore. I can add it can save it

But after it has been added and i wanne edit it again, i cant: it keeps loading the card config:

I also cannot use the raw editor then, it just seems blank.

When i remove the card, im able to view the raw config and edit it again…

Removed card:

RAW Editor:

Does this card only work in the YAML mode?

EDIT: Meanwhile i have found out that the problem only occurs when i open the view with the actual card. i can use RAW edit on all other views as long as i wont go to that view that holds the button-card. Once i have opened the view, i think the card loads and things brake. After that when i go back to check config, the config seems fine and i can open the raw editor again from all the other views till the moment i open the view with this card again, I hope u understand me, my language is not native English.

Here is the card config:
