Numbers of products not updating

Hi!

For a while now we’ve had problems with numbers in the filter not updating directly, or new categories/attributes not being added to the list in the filter. We’ve cleared cache, temporarily disabled the cache plugin we use just to see if that was the problem, but to no avail. The numbers seem to update after a few days, but the new categories do not show up even after that period of time.

Could we get some help with this?
