How to resolve hundreds of unwanted blocks?

LibreCAD keeps creating a new block definition whenever the user copy-pastes or cut-pastes an instance. I think this is an old bug that came back in version 2.2.1.

My question is, what if we already have hundreds of unwanted blocks created accidentally. Deleting and recreating them is a waste of time. How can we fix it, say, relink them all to just one block?

Can you provide a procedure to trigger this bug behavior?

I tried:

1, File > New, create a new drawing;
2, Draw some lines;
3, Create a new block with lines from Step 2;
4, Edit block from Step 3;
5, Closing the editing window.

Expected:
1, only a single block after Step 5.

Hi dxli.
Thank you for the help.

This is not about editing a block, but about copy-pasting (with Ctrl + C) or cut-pasting (with Ctrl + X) a block in the main drawing.
So after step 5. Try copy a block to other location. Or try cut and paste it. This is a very common workflow in architecture.

Example scenario. Say your building has 10 doors all of the same width of 90 cm. You create a block of that door, and name it for example "door 90". And place the block on each of the wall openings. Inserting the door block from the block list or using Move/copy command works perfectly fine. But when you try to perform copy and paste a door block (Ctr+C or Ctr+V) from 1 opening to the other, strangely LibreCAD created a new block "door 90-1", then "door 90-2", then "door 90-3", and so on. You realize it too late when you have 10 doors each link to a different block, not to the same block.
