Welcome to the Q&A Forum

FWIW and from own personal anecdotal evidence when a sitewide link gets picked up, it just takes a bit of time for Google to see the disavow and also to see that it's been removed.

Have you had any kind of penalty notice in your GWT panel for this site? If you haven't then that's a bonus,

Do you need to remove the Disavow for any reason? Then why risk moving it?

Have you also checked with other backlink checkers to see what they are seeing? Lots of tools refresh their data at different rates - so that may help you.

Good luck.

Thanks Everett - sorry about delay in coming back to your response.

This 301 issue was one if the things we were worried about (along with a ton of others) so we can at least be a little self-assured that we're prgressing on all fronts and not leaving a gaping problem that will continue to dog us.

Cheers
