My windelov always reproduced at the same rate that my regular java fern did when I had them both growing in a 30 gallon. The plantlets developed both on the lacy part and the main parts of the leaf, from what I remember... but that was a few months ago and most of the time, I didn't see the plantlets until they were floating around.
I don't think there's anything wrong with your Windelov. If it's producing babies like crazy and it doesn't look bad, it's probably just really happy. That plant looks great in a big bunch, so just keep tying those babies... you could have a really impressive ball of Windelov if you wait long enough.
