Crop tool confuses the width and Height aspect ratio.

One simple task that I can do in photoshop in a second has baffled my mind in Lightroom classic. 

I have a picture that was originally a square 1-to-1 ratio with high resolution. (like a 5 by 5 passport picture)

Now I want to make it 3*3.5 but what it does is in fact the reverse of what I want which is 3.5*3! It still shows the ratio is 3*3.5! Somehow it insists that the width should be greater than the height!

I tried to change and try this with export tools under image sizing and give it 300px to 350px ratio and it is still not working! 

Any insight will be appreciated.
