Thanks Alex,
Appreciate the look through. Speaking from memory, but I believe the problem was removed around the 20th of January 2019. I have been manually requesting the indexing of the page in GSC every two weeks since that point, so as much as I would like it to be a waiting game, I have a feeling there is still an error and that leads to my next point.
Great suggestion on retaking a look at URL inspection tool. When I used the tool previously, I did not tab over to the "screenshot" mode, and that seems to be where this is all coming from. Take a look at my screenshot. The page is full of copy that matches up to that spammy meta description. My next two questions would be, how could this be overwriting my descriptions when I don't see any of this on the live site or in the page source? Additionally, there have been no security reports in our GSC account, is that normal?
