Yea that certainly shouldn't disapear. Where is RetroArch saving your configs or is it denying the save all together? if it's denying the save, try updating LaunchBox to a new version or change it's folder location. You can also go to the RA settings and change the config path your self to point to the folder you want. If it is saving them in a different folder, you can also just change the config folder to where ever they are at.
I apoligize if this seems basic and / or if you've stated, but just to make sure, you are on 6.2 and before closing out the Associated Platform you are pressing Ok rather than Cancel? It's also worth asking where you have your LaunchBox install located. If it's in the default location then it may have some permission issues when it comes to saving settings. Do you remember exactly how you added then closed LaunchBox so that we can try and test it on our end's?
When I run RetroArch by itself it will save the per core in the configs folder. When use LB it saves in the root. I am running LB 6.2
