Font/style changing after every space

Scrivener Scrivener for iOS
1

I am using a homemade font, which is working without problems on Mac, both on Scrivener and on other apps. It is also working without any issues on other apps on my iPad.

However, on Scrivener on iPad, when I hit the space bar, Scrivener changes the font from the intented one, to helvetica.
The font is installed and works otherwise without problems.

I have tried selecting a piece of text that I have switched to the correct font and setting that as default formatting. But that did not fix the issue.

And I have tried creating a new paragraph style on Mac, that uses the desired font. And the iPad app recognises the font and shows it correctly, but still, when trying to type on iPad, hitting a space changes the font. (The style panel still whows a tab on the correct style, just the font changes.) Which does not happen on mac, when using the style on there.

I’m running out of ideas to try, so I’m turning to this forum for help.

Have you tried setting the default format in iOS Scrivener to some other font? The idea being to determine whether the problem is with the specific font you’re using, or with the default formatting mechanism itself.

I have, other fonts don’t have the problem. Neither when using them manually, nor when setting them as default. And even with other font as default, scrivener switches back to helvetica, when I try to manually use my own font.

So I assume that would suggest the problem is with the font somehow, but I don’t know how ios scrivener reads the font differently to any other apps, including mac scrivener, that causes it to be the only app with this issue?
