Can Hubspot conversion events be used to optimize Facebook lead ads?

I’m jumping in here because this still seems to be an issue. Has anyone managed to solve it this year?

What I am seeing now is that Hubspot are serving the pixel from the embedded Hubspot code on pages. But when it does that it looks like the Hubspot lead events created by the browser pixel are using inconsistent event labels, such as LEAD instead of Lead. And this is messing with my data and existing campaigns. As LEAD and Lead are seen as 2 separate events so now the campaigns need to be rebuilt to optimise for LEAD. Is anyone else seeing this too?
