I've tried to reproduce the problem, but I did not manage to - linux, windows, with the mods in various ways, different languages, no problem. So, I cannot do much at this point I'm afraid.
Maybe a few more details could help:
- Version of Factorio & the plugin
- Platform (windows, linux, macos, steam / non steam, versions)
- Language of your Factorio
- Maybe - other mods loaded? (I don't believe that other mods can cause but I don't have much ideas at this point)
