Filter many offline data sources with one filter

Hi Everyone

I've built an application with discovery but I had to do some modifications in designer; so I exported it

I had 3 datasets in Discovery so now I have 3 Offlines datasources in Designer

I'm able to filter many data sets if they are all comming from the same data source, but if I tried to filter a datasource with an item comming from another datasource, it doesn't work (In Discovery I etablished a dataset link between these 3 datasets but apparently it's totally useless)

Any idea of how could I do that?

Thank for your help
