Need a small conversion done from UNP to BHUNP please

[tejano2828]

I tried to do it myself instead I deleted the main body and had problems installing the new body.  I looked at youtube videos but I find bodyslide so confusing.  please it's a small mod

if anyone can convert it it would be much appreciated.  Her  is the file.  It's for Skyrim SE

BHUNP Ver 4 Mizuryu Key Outfit.7z

Forgot to mention, yes it says BHUNP but it's not.  When I open it up on bodyslide it's clearly UNp or UNNP but def not BHUNP they did not convert it properly and I forget where I  got it from.
