How to set a 5×4 crop?

I'm new to LR, just installed it. I'm trying to get a 5×4 crop to post pictures on my IG. When I select "custom" under the aspect ratio tab nothing pops up. Is it suppose to be like that? I'm watching YouTube videos and when people select custom something pops up where they can pick their own aspect ratio
