Battle maps

Very good afternoon/night or day. I had been wondering about this for a while and the truth is I hadn't thought about asking here since there was no answer anywhere else.

I have wh3, wh1 and the Tomb of Kings DLC, and every time I do a battle in the desert, the desert or similar map does not appear, but rather a forest or jungle map and it is repeated in all the battles, it also happens to me at most against the skaven in their underground, the map is supposed to be an underground but not a repeated forest.

You know what may be the cause of these repeated maps, it overwhelms and bores me to fight on the same maps over and over again. If you can give me a solution I would greatly appreciate it, and if there is a mod in the workshop that adds maps that would be great.

Greetings!!
