Font has a different xHeight in After Effects compared to any other software

Hey all, not sure if this is an Adobe bug or a potential issue with the font but I'm having an odd issue with After Effects where the height of a font is appearing differently in After Effects compared to everywhere else.

As you can see from the images I have two words that are written in two different fonts in Illustrator. The fonts are actually the same base font but 1 of them is a custom cut (to adjust kerning) that we had created by the foundry. In Illustrator, InDesign, Photoshop, Premiere and everywhere else I've tested it both fonts have the same height when set to the same point size as intended. But for some reason in After Effects the newer font with the customisation appears to be about 3% smaller in height.

I have tried thise in multiple versions of AE, and on both Windows and Mac and the issue is consistent.

Not sure if this is a bug or an potentially Afer Effects quirk effecting a setting within the font itself. Any help would be great.
