I made a text component where the default colour (set in the parameters) was red.
I placed the component onto a page and changed the text colour to dark grey.
I saved and left that page.
I edited the header.
Came back to the page above, the text had reverted to red, overwriting the grey I’d picked.
I’ve changed the component parameters to default to grey for now.
This is part of a larger issue that has been fixed on the latest release, which is not currently out. It should all be good in the next round. Thanks!
