Grapbics problem with openandromaps

[Hispanico]

I use offline maps from openandromaps, download from page

https://www.openandromaps.org/en/downloads/europe

but see my screenshot, map has green lines on all map.
This not happened if us eg map LoMaps

There are some settings in option to avoid this graphics problem ?

Thank and good sunday

This is not a mistake. It shows you a nature reserve. If you don't want it then you can disable it in the theme. Borders + special areas.
