Shirt "tags" limited to 3 words?

In the “TAGS” Section, I was able to list long tail keywords. Now, no matter what I try, it is limited to only 3 words! This is NOT good! Some of my older listings have 3-7 keyword tags. When I try to copy/paste them, it divides the words, even though I use commas between tags.

Example: 6 word tag: “Plus size women’s shirt for Mom”, is broken into: 2, 3 word tags: Plus size women’s, shirt for Mom.
I can’t use proud mom t shirts, as the tag breaks it into: 2 tags, proud mom t, shirts,

Please, Can this be fixed?? Thanks!

This sounds like a bug. Can you please let me know the Design ID for which you are experiencing this problem?
