Homebank has somehow defaulted to Arabic - no other apps affected

I have no idea why the interface has defaulted to Arabic, or how to fix. No other apps on my system are affected. Even the app icon entry in the launch menu has 'homebank' in Arabic.

It's been working fine for several years, including just fine when I updated to 5.6.1 and just came to do my finances this month and found that it's in Arabic.

Homebank 5.6.1
Linux: Pop!_OS (Ubuntu)

Installed via:
sudo add-apt-repository ppa:mdoyen/homebank
sudo apt-get update
sudo apt-get install homebank

I understand that there is no option to set the language like most other apps I've used. I Have read the following questions and tried to find the locale dir to delete but can't locate the relevant files/folders
https://answers.launchpad.net/homebank/+question/59090
https://answers.launchpad.net/homebank/+question/26196

Tried this, but it says no such directory:
LANGUAGE='en_GB:en' ./src/homebank

I ran the following but none of the locations showed up in the examples in the above questions.

sudo find / -type d -iname homebank

/usr/share/doc/homebank
/usr/share/homebank
find: ‘/run/user/1000/doc’: Permission denied
find: ‘/run/user/1000/gvfs’: Permission denied
/home/snuffy/Documents/Homebank
/home/snuffy/.config/homebank

Any assistance anyone can give would be great... otherwise I'm a bit stuck... considering I don't really want to learn Arabic!
As you can perhaps tell I'm no Linux expert but if pointed in the right direction I can usually do what's asked.

Thanks.
