Setlocale warning message

Hello,

I’m using the latest version of dietpi (as of 2 days ago installed…sorry, not sure of the exact version). I live in North America and thought I would add a US locale to my dietpi config. But reading the documentation I see that I need to keep the GB locale for updates (makes sense). So I added US and kept GB. But now that I’ve done this I’m noticing the following warning message whenever I do anything on dietpi (updating software, doing any dietpi config changes), on LXTerminal I’m seeing this warning:

/bin/bash: warning: setlocale: LC ALL: cannot change locale (0.UTF-8)

Is this warning due to the changes I did or is this warning a red herring and something I can ignore?

Thank you.
