Lektor adds text from po files when building on debian 11 / python 3.9.2

See https://community.pages.tor.encryptionin.space/

My server is running deb 11 and python 3.9.2, no matter how I have installed lektor the above is the result.
My local dev whonix is based on deb 10 and has python 3.7.3, I am running lektor from source, the result of building is what it should be (no extra po file text)
