How do I remove decimals from altitude in watch face created with Faceit Android?

I created a simple watch face a while ago for my Fenix 7 using faceit, amongst other things it shows altitude. At some point after an update the altitude began showing decimal places which is very ugly, the value also seems to be quite wrong (i.e. right now it's showing 142.249634 instead of about 15m.

I've tried re-installing the watch face and re-creating it fresh in the app and installing it but the bug persists.

I'm on the latest app (Connect IQ 2.34) and firmware (20.22) versions.
