Can’t update linked number

Hi
First, I import one keyword then I update target URL for it, the Links Limit is 1

Then I changed Links Limit to 100 and update again, there are 35 keywords found on the site. But linked is only 1. What ever I do – Link all, recount, update…
But it not update the linked number.

There is only 1 link matched in all articles.

Please fix it.

Thanks
