So I'm trying to import from the same database, from one table to the other. But as you can see below, it will not populate the left column.
If I set this up exactly the same on a test website (The one you have access to), it works.
Any idea what could cause this? I tried a lot of different settings and combinations. Just seems like a bug on the one website where it doesn't work. Also tried it with other tables.
Cheers
