Comment:

 Hey @frankakot1, Welcome to Trac, and thanks for bringing this up.

 I was able to reproduce this. Here is the report:


 This is a bug specific to WordPress 6.6.x where tags with special
 characters are incorrectly matched during post save.

 Steps to Reproduce:
 1. Install WordPress 6.6
 2. Create three tags:
   * "kid+" (becomes slug: kid-plus)
   * "kid" (becomes slug: kid)
   * "children's" (becomes slug: childrens)
 3. Create a new post
 4. Add tags "kid+" and "children's"
 5. Save post
 6. Check tags - "kid+" becomes "kid"

 Expected: The post should keep "kid+" and "children's" tags
 Actual: "kid+" is saved as "kid"

 However, this has been fixed in the later versions after 6.6.
