black tiles when downloading map

[rawalpundi]

hello,
when I download a map for offline use, I sometimes get black tiles,
is there a way to re download the missing tiles ?
best regards

thanks,
in the "Map Tweaks" menu, I don't have "Refresh Tiles",
only "Map mode", "Map calibrator", "Map Datum", "Night mode", "Enable/disable GPS scroll"
