After update to k2 v2.6.8 ; home page and pages that have 2 or more k2 categories; Comments Counter has Problem and show incorrect "be the first to comment"

Hi. Just tested and it works for me. Ensure that:

1. You are not using any custom K2 comments plugin.
2. You have not any template overrides to K2 layout files. If you do you might need to update them.

yes when use komento or jcomment the prolem occur
but what change in k2 2.6.8 cause this problem and how can i fix it?

Since the issue occurs when you use third-party comments you need to ask for help at the developers of those plugins. There is nothing to be fixed in our side since default K2 comments work fine.
