What is the issue with shift + NUM key combinations?

Hi,

I’m trying to make an event fire on ctrl + shift + NUM 7, but for some reason it does not work. Whenever I press the ‘shift’ key the NUM 7 key event gets blocked. In fact, when I connect the shift key ‘pressed’ event to a ‘print string’ node, the string prints once when I press shift (as expected), but then prints again every time I release the NUM 7 key (or any other NUM key). Why is this?

All other settings are default, I made sure the shift key event does not get consumed by any other BP.

Other people found that their keyboard does not support certain key combinations, but I tried this with a different keyboard: same result.

There are no action mappings set in the project settings.

I have the same problem shift and num combinations don’t work for some reason

Can someone please help us with this ordeal? I am having trouble completing my client’s task because of this engine barrier.
