I have a piece of paper written in multiple languages that is consistently missing language indicators. However, I can't seem to produce a new piece of paper that is also missing language indicators.
In the screenshot below, I have left some unblurred text in both Common and another language (I think it's Martic). I asked a player who reads both languages, who tells me it appears to be written in one (completely legible) language to them.
I tried starting a new paper in Lapin and swapping to Common, but the language indicators do appear for both languages. Similarly, I wrote some Lapin text on an old paper that began in Common, and the language indicators still appear. I also checked a Nivalis folk song book, a piece of paper written entirely in Martic, and Harris' ad for Song's post office, and all have indicators.
The foreign language text in the paper below behaves like other foreign language text for me (it scrambles differently each time I open the paper).
