See https://www.wikidata.org/w/index.php?title=Q4115189&oldid=270323178
The main coordinate location statement links 1N 1E to https://tools.wmflabs.org/geohack/geohack.php?language=en¶ms=1_N_1_E_globe:earth which works fine
The qualifier links 52N 5E to https://tools.wmflabs.org/geohack/geohack.php?language=en¶ms=52%C2%B0N,%205%C2%B0E which doesn't work.
I would expect the qualifier to link to https://tools.wmflabs.org/geohack/geohack.php?language=en¶ms=52_N_5_E_globe:earth
