Anki 2.1 and 2.0 show different streaks

[MrPiethon]

Problem description or Feature request

If I open up Anki 2.0 on my desktop it shows my actual streak of 54 days. If I sync and open it up on my laptop that is running Anki 2.1, it shows a streak of 4 days. It is showing that I have no studied and cards on certain days, but in fact I have. I am expecting on Anki 2.1 to show the same streak of 54 days.

Additional steps taken:

• Deleted all the decks, but previous streak/study information is still visible
• Tried deleting the addon in addition to the decks, and then reinstall addon -> previous information still retained
• Tried exporting the deck from anki 2.0 with correct streak, and importing it into 2.1 -> still wrong streak
• Did a clean install of Anki 2.1 (latest beta) and installed heatmap, then imported deck -> still wrong streak information
• I downgraded anki 2.1 to 2.0 and installed the addon and everything is working as intended, but for some unknown reason it does not work correctly on 2.1.

Questions:

• Could it be that Anki 2.1 heat map addon does not count cards that were rescheduled using using an addon like quick re-scheduler?

Other:

• I can provide the collection file for troubleshooting and replicating the error

I'm seeing similar issues with number of cards not being correct - 2.0 is showing the correct count but in 2.1 it's off - both in looking at built in stats, and by searching using "rated:1" the counts are quite a bit different. I think it might have to do with new day start time but not sure

I'm not sure if day light savings had a part in it, but I fixed it by going back an hour. Everything seems to be working right now.
