[SOLVED] Stellarium: Unable to add new location

[BinocularSky]

I'm getting some weird behaviour from Stellarium 0:21:3. (It's years since I installed it on a new computer, so it could be user-idiocy 🙂 )
 

I'm trying to put my location into it. I insert the correct Lat, Long, & Elevation, check "Use current location as default" (and I've tried not doing that), insert Name of town, etc., then when I click on "add to list", it does so, but changes the Lat and Long to what it was previously (it seems to "think" I'm in south London!).

Any ideas?

Edit: Solved by editing the user_locations.txt file.
