Odd Vertices and Facescount in Statistics panel

I stumbled across this when i exported my whole level geometry to optimize it. I made my level out of single pieces first. Then i exported the single pieces, and have unioned and optimized them in my graphics software where ever possible. The vertex and faces count has sunken to around the half of the original dataset by that.

And now the funpart. After deleting the old geometry and importing the new geometry into the level, the tri count gots doubled in the Statistics panel instead of sinking. With half the mesh data. From around 250k tris to around 500k tris for the whole level.

The only thing i did was to remove the old geometry and to add the new geometry. The old geometry is completely removed.

I checked the other objects in the levels then. And also here the faces and vertices count is not longer valid. I have a spikebowl for example that has in a fresh level around 1000 tris and 2000 vertices. When i turn off one of these spikebowls in the trouble level then the Statistics panel tells me about 30000 tris that gets removed …

What is more dramatic is the drawcalls. The Statistics tells me about 21 drawcalls for a spikebowl in the trouble level. In a backupped level it`s just 5 for the same object at the same location. Question is, is the value correct, do i have a geometry problem in the level? Or is it wrong, and i get wrong values by the Statistics panel ?

Somebody a clue what is going on here? Any good advice for this situation? What should i do now?

Lightmapping has fixed the issue. The values are still a bit too high, but back to something more normal again. Odd.

Have it. This was caused by too much point lights. I have known that they add to the drawcalls. But i haven`t known that they add to the faces and vertices count too.
