Button spacing shift and nav misalignment

Site URL: https://tangerine-iguana-kwg3.squarespace.com/

Hello!

I noticed that there was a sudden shift on spacing for buttons across my site + nav bar roll over. Would someone be able to advise how to fix this issue? 

- Essentially all buttons seem to have an extra space at the top

- The hover bar below the nav overlaps with the text. 

It's not really clear to me how this happened since I haven't made any modifications to my site in some time. Would love to receive some guidance on this on how to potentially fix this. 

Thanks a lot 🙏

Try change button font name.
