Issues creating unique letter spacing for P3 text

Site URL: https://lemon-clownfish-nanb.squarespace.com/

I have unique font styling for my site where the letter spacing for p1 and p2 needs to be quite high.

For p3 text I would like it to have normal spacing between the letters. I have used the code below and tried several different variations but no luck. I do have a custom font uploaded for the header fonts but I don't see why this should affect any of my paragraph formatting.

Code that isn't working:

p3 { letter-spacing: 0px !important; }

The only way I could get the spacing to reduce was by targeting the specific block with the code below. This doesn't really work for me though as I'll have quite a few areas with p3 text on my website and it doesn't make sense to target everything individually.

Any ideas?

code that works:

#block-yui_3_17_2_1_1729029081744_69932 { letter-spacing: 0px !important; }

That worked thanks so much.
