Variable Font Problem in InDesign v19

Hi

I created a document in InDesign 18.4 which uses Gal Gothic Variable font from Adobe Fonts. However when opening the document in InDesign 19, the font is messed up.

For easy comparison I created a new document in 18.4 using dummy text, and then opened it again in 19. Results are shown below - first image is Indesign 18.4 (appears correctly) and the second is InDesign 19.

This occurred in ID19 and 19.0.1 so it hasn't been addressed.

Has anyone else encountered this?

UPDATE: Only happens with Gal Gothic Variable font weights from Demi and above, and doesn't occur with other variable fonts such as Acumin.

Thanks
Richard
