Remove host/computer

I changed system name of my PC and this resulted in an extra host, how do I remove this? It’s essentially split my data into 2 categories and I’d like for it to be 1 again. Do I go into one of the files and remove the name or something?

Sorry about that, there is no easy way to do this at the moment.

If you have some programming knowledge it can be done (export buckets -> merge the exports -> import), but otherwise we suggest you just live with it for now.
