Incorrect count of number of nodes

The count is incorrect for the number of nodes per category.

For Ubercart managing roles (I was not able to track down the exact permission that causes it), the count is 3 times than it should be (27 instead of 9, for example). For others, the count was normal.

When I changed the number of images per product to 2, the number was doubled. So, the count for above mentioned role was 6 times the normal count (for example 12 instead of 2) and for all other roles the count was doubled (4 instead of 2).
