Add existing vault dialog does "nothing"

That works. It’s telling me about upgrading the vault. Is it safe for me to post that file? I suppose I can change the password, so here it is:

{
  "scryptSalt": "Xxxxx+=vvbbb",
  "scryptCostParam": 32768,
  "scryptBlockSize": 8,
  "primaryMasterKey": "[54 Didgets]==",
  "hmacMasterKey": "[54 didgets]==",
  "versionMac": "[43 Didgets]=",
  "version": 6
}

PS: sorry for the late reply, I was prevented from posting so many replies in my first day.
