I'm still having this issue. I would recommend taking a look at the way the API is called. I can see that there is a patchDescription, patchDuration and patchRole that are all calling the same endpoint that updates all the fields simultaneously. I believe the reason we are having this issue is that we are calling this endpoints with outdated values.

From the top of my head I think we could either include all the fields when updating a node (this can be problematic if multiple people are updating different fields in a node at the same time). Another option is to change the backend so that it only updates the fields we send in the request. If the backend already does this then we need to change our requests to only include the fields we want to change, and not all of them.
