Slow Loading TopoActive 2019 Maps ongoing issue

H There,

I wonder if someone could help me with ongoing issue of TopoActive Maps on my Garmin Fenix 5 Plus. As there some other users notified those maps response is very slow for zoom in/out and it might be due to some old files located on my watch. The trouble is I am not sure which files need to stay and which removed. I have done screenshot from my Garmin Express app to show what maps are installed and also another screenshot with folder directly on my watch.

Currently I am using free OSM British isles maps taken from https://shop.talkytoaster.me.uk/product-category/free/  which load very fast but I travel often across Europe and free Garmin TopoActive maps would be nice to have. The thing is when I go to map settings I am presented with option of :

- Worldwide DEM Basemap

- TopoActive Europe 2019.10 North East

TopoActive Europe 2019.10 South West

-  OSM British isles

I am located  in UK, which is not in South West of Europe as far as I concerned and strangely, this the one of of two TopoActive maps which works.( still slowly and lagging) 

I would appreciated if someone tell me which maps need to stay, and which need to be deleted or give me any guidance on how to figure out this issue. 

Thanks
