Cohorts in network of networks do not appear in Variables page cohorts filter list

[BrendaHijmans]

What version of EMX2 are you using (see footer)
v10.103.1

Describe the bug
If a cohort is linked to a network and that network is part of a network, that cohort is included in the network of networks.
For instance: cohort ELFE is part of network LifeCycle. LifeCycle is part op EUChildnetwork. Therefore ELFE is part of EUChildnetwork. However: the list of cohorts on the variable page of a network of networks does not show all cohorts that are part of a network of networks.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://data-catalogue.molgeniscloud.org/catalogue/ssr-catalogue/EUChildNetwork
2. See that 49 cohorts are involved
3. Click on 'Variabes'
4. Click on 'cohorts'
5. See that the list does not include all 49 cohorts.

Expected behavior
All cohorts within the network of networks should be included in the cohort filter on the variables view
