Data Permissions to Strava - issue, help?!

Hi there, looking for a little help from the community. For about a week my rides on Zwift are not automatically uploading to Strava. It had worked fine for about six months before that. I’ve been all over the partner integrations on both platforms, and as far as I can make out, the issue seems to be this option list (see attached image) wherein the critical one is ‘grayscaled’ out, meaning it can’t integrate. Having found this I’ve been back all over the permissions and options in both apps and can’t seem to find a way to get that opt in live - any thoughts / tips / solutions?
