Topic: Tags showing different/the wrong number of images

I looked, just as an example, for "lion" the result was 300 images, i clicked on one and now there were 21438 images connected to that tag. clicked on it and the overvieq page shoed 300 again. Same for many other tags one had 151 in the overview and 298 as i ckicked on an image. why are these numbers so different?
