Can you repeat the problem? If so, what are the steps?
In the White Balance filter, you can’t type a color temperature without entering a comma.
For example, if you wanted to type 6,500K (6500K) and type “65”, it won’t take any more digits. It will only accept “6,500” entry (comma is mandatory).
This existed since the user interface change. I forget how far back that was. It’s affected at least the last two versions.
You should be able to type a value without requiring entry of the thousands separator.
