Tooltip color

Hello,

Great plugin, thanks for the hard work ??

I’m facing a strange behaviour when trying to change color of the tooltips for a button. It seems to be set to #fff by default and when I try to set it to anything else, the page says that changes are saved, but if I reload the admin page, it comes back to “empty” and on the front page it remains white ??

Any hints ?

Thanks for your help and support
