Subject: undismiss Item and recover learning information

Question:

I have by mistake dismissed the wrong Item. So I have lost the correct learning status.

Is there a way I can cancel my mistake? As if I never dismissed it? I tried with Edit. But I did not found a possibility there.

Thank you.

Answer:

Always be careful when editing repetition history. It is easy to make changes that are hard to reverse. In your case, deleting recent records from the history should work. You should delete the records marked red in the picture:

When I press Ctrl+E, my expectation is, that now I can see a window with:

ElNo=2530 Rep=2
ElNo=2530 Rep=1
Reset
ElNo=2530 Rep=8
ElNo=2530 Rep=7

I expect the same rows, as if I press Ctrl+Shirf+H (It is the picture above).

But when I press Ctrl+E, I only have lines for

Rep 8 and
Rep 7

So as I do not want to delete Rep. 7 and Rep 8, but that, what was happened later (after Rep 8) and I do not have entrys in Ctrl+E after Rep 8, I can not delete anything.

Can you help me?

In the meantime I have deleted the row "ElNo=13635 Rep=8 Date=26.05.2019 Hour=19.758 Int=233 Grade=12 Laps=1 Priority=3.0557"

So my exceptation was, that I can go on as if I never dismissed it with Rep 8:1 or Rep 9:1. But there is still a reset and begins with Rep 1:0.

That is not what I wanted to have. Did I miss anything?
