Quantize Panel Issue

Hi, all! Can’t seem to get the Quantize Panel to work properly. Currently rocking Nuendo 13. Haven’t had this issue in older versions of Cubase/ Nuendo. Can’t seem to get the quantize panel to work while trying to quantize some drums. Everything in a folder, and group editing applied. The panel doesn’t do the little ‘dropdown’ like it should/ usually does.

Any help is appreciated!
