Let's say I have this:

Source: Cooling

Target: kylning

If I select these and press Ctrl-F2, a new term is added to the termbase. I can find it using Termbase Search, so there is no problem there.

So far so good. However, I want the term to be lower case. So, I edit the English term in the Termbase Viewer (in Studio) to "cooling" and press the little check mark.

This gives me a popup: This term already exists in the termbase. Do you want to merge the entries? It has two buttons: "Duplicate and "Merge". The problem is that whichever I press, I get this error message:

Script error

Line: 8749
Character: 10
Error: The entry number does not exist in this termbase.
Code: 0
URL: .../SDL/MultiTerm14/Editor/modern/bundle.js

(I shortened the URL)

After this, the term is suddenly gone and can't be found in Termbase Search any more.

What is going on here?
