As shown above, for users who have CX enabled, the compact interlanguage list shows many gray interlanguage links. This may be inconvenient for users who would like to have more options to read existing articles in other relevant languages. Restricting the number of gray links in the list may be helpful.

This issue started appearing since we increased the number of remembered previous languages from 5 to 9 for ULS. Now we restricted the maximum number of gray links to 3. Hope that helps.
