Ionic 1 UI only updates half the text?

Hi All,

My app is doing a weird thing. See pictures:

The number is 3750 in the bottom picture, but somehow the UI doesn’t render the top part of the numbers?
I’ve upgraded ionic according to IOS 11 recently, but I don’t know if that has anything to do with it. It has not always done it.

There’s no problems in browser. The issue is only on IOS.

Any suggestions?

UPDATE: I just found out, that it also happens in safari browser on my MacBook Pro.
