Holy Geez how in the world did you tear a hub apart?! Which model strida do you have? because my Strida 5.0 16 inch wheel hub has these funny elongated holes which two spokes go into each one but didn’t have extra holes between like that though. Never had a problem with them but then I moved onto the 18 inch wheels and the hub on those have no empty hole spacing all spoke holes only. It’s a solid piece of metal and after 4000km’s on them they’re still fine luckily 
. I did 2000km’s on the other one before i upgraded (2k a year of commuting). But yeah i’d contact ming about that to let them know about your model so they can offer replacements. You basically need a new hub and relacing a wheel isn’t the most fun if you don’t have the equipment.
If I stayed on my 16 inch rims I would have upgraded to those Strida LT mag wheels! no more spokes to break!
