Heatmap counting a random date

PinkDucki commented 1 year ago

Problem description

I started using Anki yesterday, and got started on my first deck. Just now started a new (second) deck. After learning 10 cards from this new deck I went back out to the menu where the heatmap is. For some reason it says that I have 1% days learned, and I can scroll back on the years, back to 2021 where I have a single day learned. I am very confused cause I literally only made my account and started using Anki yesterday.

I'm not sure if this is an Anki issue, or a heatmap addon issue, but when I go into the statistics window, no data from before I started shows up and I can't even go back to the 2021 page, so it leads me to believe its probably a heatmap issue?

Checklist

[x] I've restarted Anki to see if it helps
[x] I've verified that I use the latest version of the add-on by redownloading it from AnkiWeb
[x] I've verified that I use the latest version of Anki by checking at https://apps.ankiweb.net#download
[x] I've tried to disable other add-ons to see if there are any interactions present
[x] My issue disappears when I hold shift while starting Anki. *
[x] I've checked if anyone else reported this problem before by looking through the issue reports. I also checked to see if there is a section about known issues in the add-on description, documentation, or README. *The heatmap doesn't exist when starting anki while holding shift, so its impossible for the issue to be there

Dropping by to say I'm experiencing the very same issue. I created my account and started using Anki in October of 2022, but the "Days learned" stat is skewed low because of a random day in 2021 when supposedly 17 cards were reviewed:

I will add that the "Ignore Data Before" fine tuning option does nothing to affect it.

UPDATE: As it turns out, this is an issue when you use a deck shared by someone who accidentally included scheduling information on some cards, not an issue with Review Heatmap. @PinkDucki I was able to fix this easily with the following:

Backup all your decks / the whole collection.

Press Ctrl+Shift+; (the control key, shift key, and semi-colon key at the same time) On a Mac, press Command+Shift+; to open up the debug console.

Paste the following code into it and replace that long number with the timestamp you require. I found out the required timestamp from here.
mw.col.db.execute("delete from revlog where id < 1460683240826")
mw.col.mod_schema(False)
Press Ctrl + Return to run it.

Click Tools -> Check Database and finally upload your collection to ankiweb at the next sync.
