Number of Co-Occurrences differs with some notations

[guitarster]

Example: https://coli-conc.gbv.de/cocoda/app/?fromScheme=http%3A%2F%2Fbartoc.org%2Fen%2Fnode%2F533&toScheme=http%3A%2F%2Fbartoc.org%2Fen%2Fnode%2F18785&from=http%3A%2F%2Frvk.uni-regensburg.de%2Fnt%2FRB%252010177

If I select RB 10177 I get two Co-Occurrences (there are 9 when I check the notation at the API: https://coli-conc.gbv.de/occurrences/api/?member=http:%2F%2Frvk.uni-regensburg.de%2Fnt%2FRB%252010177&scheme=http://bartoc.org/en/node/18785)

If I select RB 10180 I get two Co-Ocurrences as well (9 at the API, too)

But, if I select RB 10183 I get 5 Co-Occurrences (9 at the API)

I'm a bit confused why there are only two Co-Occurrences in the first two cases and 5 in the third case, although there are at least 9 Co-Occurrences in every case...

The results seem to match now, at least for me. Could have been a caching issue maybe? However, I'm a bit confused about the cutoff, as the API usually returns more results than are shown in Cocoda. I'll check this at some point.
