Describe the bug
We had a few people missing data from our raid on Sunday 7/5/2020. Today, before our MC run, we had one of our officers who had the data, push 2 week merge to our guild. It appears that all data from the last 2 got duplicated.

1. Addon Version and Release: 3.1.1-r47 )

2. What are your DKP Modes? (screenshot preferred)
   
   

3. What is the issue you're seeing
   Entries are duplicated (highlighted blue in the first image), we don't allow negative dkp

Not denying there's an issue, but I'm not able to reproduce in my test environment. Was the officer that did the sync have r42 installed?

@jvolkenant So... I see Qual has the latest indexes in some of the tables, but they are rockin' version r37 which introduced this issue.

                               ["Quel"] = {
					["previous_dkp"] = 0,
					["dkp"] = 0,
					["class"] = "None",
					["lifetime_gained"] = 0,
					["role"] = "Caster DPS",
					["version"] = "v3.1.0-r37",

Important to get everyone to update to the latest version. Sorry about this error. One of the reasons why I changed the minor version to 3.1.1, so that the addon would yell at people out of data. Based on your file, there's a wide swather of versions.

Quel is traveling, and should have tables before the push that occurred today and work out how we can get synced and up to date. We'll tell our raiders to get their versions updated as well.

Thanks
