Assigned Arrow Keys not working in Export dialog

Hi!

To adjust to my workflow I selected the “Pro Tools” - keyboard preset.
This maps the left and right arrow keys to move the playhead to the begin or the end of an selection.

When I go to Export-Audio Mixdown the arrow keys keep controlling the Transport shortcuts instead of my cursor in the textfield.
Making name adjustments a bit annoying…
Also makes me really anxious about making my own keyboard setup. The Export windows should not allow any keystrokes outside that window…

Happens on Cubase 10.0.5, High Sierra…
