There is some problem with few sceneries on SWDR, but if I have a good memory Łęczyca isn't one of them. So I think you have old version or bad hash of this station, download one more time files and change them with old one. I hope it will works.

Ok where can i download It?

Hi,
Normally the official sceneries are updated automatically.
Unofficial sceneries  can be downloaded here in the respective contribution: https://td2.info.pl/scenerie/

Due to 2020.1.1 some sceneries may not be updated yet. In this case you can only play them when the author of the scenery has updated them.

In that case with Łęczyca: You have an old version. The current version has the hash 635fc6de so you need to update it.
There was also a topic about it: https://td2.info.pl/english-boards/arkadia-zdroj-2012/
Try this:
1. Close simulator,
2. Navigate to  C:\Users\<username>\AppData\Roaming\OnRailTeam\TrainDriver2. You can use Windows+R and enter %appdata% and press OK to open "Roaming" folder
3. Open main_file.settings using text editor.
4. Find phrase: "GamePackHash":"000009" -it could be different number
5. Change value after : to "000000"
6. All official sceneries will be downloaded when you startup a simulator next time.
