Using same word twice (Please Read)

[IamNewtoYou]

Hi, I have an online thrift store, so there are a lot of items to be posted. When I use filters, I have to put the color "Pink" but when i get a piece of clothing from the brand "PINK" , it doesn't decifer the 2, so it just puts it as 1 word, so when I post a pink colored shirt that's from the brand "PINK" , It only allows 1 pink in the filters, so 1 gets left out,  hopefully this isn't too confusing
