Category doubles

When user submits a link (and he selects any category from combobox), moderator accept it, the link is in NEW category with the same name, so category duplicates.

Recreation steps:
a) login as admin
b) make 1 static site with [link-library-cats settings=1] and [link-library-addlink settings=1]
c) create few categories with some links. TestCat01, TestCat02…etc.
d) now it shows ok, eg. TestCat01/Google.com, TestCat01/facebook.com, after that i have TestCat02/TestLink1.com, TestCat02/TestLink2.com
e) logout, try to submit a link TestLink3.com in category TestCat02 selected from combobox
f) login as admin, approve it
g) in wordpress ‘link categories’ there is TestCat01 and TestCat02, so correct!
h) on website i see the structure:

TestCat02/TestLink3.com (it should be near TestCat02/TestLink2.com)
*
TestCat01/Google.com
TestCat01/facebook.com
*
TestCat02/TestLink1.com
TestCat02/TestLink2.com

Quick fix:
When U go to wordpress LINKS and you edit TestLink3.com and just click SAVE without any changes, it will be ok. Can You fix this ASAP, please?
