Weird lighting issue, diagonal square showing up when placing tokens with sight

So I've been using roll20 for a few months now and haven't had many issues but when planning out my next session I'm running I ran into a weird dynamic lighting issue I can't seem to solve. So I have this circular chamber (pic posted below) with no global illumination so a dark room. When I place a character with darkvision or any kind of light source suddenly there's this diamond like square hard cutting line of sight that doesn't match up, at all, with the dynamic lighting lines I put in place and I'm at a complete loss as to whats causing it or how to fix it without just completely scrapping the page. First below is the lighthing error, which would make sense if where the hard lines where there where lines in the dynamic lightning layer but as shown in this next image you can see those lines don't exist, in fact it seems to completely ignore these lines as (looking at the image above which is the tokens perspective) it can see right through those lines. Any idea what could be causing this?

Note, I have found when I remove the dynamic lighting lines the issue vanishes (but then off course players can see through the walls with appropriate lights. So it seems the error is simply in it being a circle. Is there a way to make circles with the shape draw tool in dynamic lighting without this occuring? I suppose I could just draw it manually as I have with most lines using the polygon/line tool but this would be far more tedious in the future if it has to happen every time there was a round room I wanted to block light from.

Circles do not work well with dynamic lighting due to the way that the paths are traced. The recommendation is to use multisided polygons . There is a script that will convert circles to polygons automatically, but that requires a Pro level subscription.
