Cannot Purge Block

I am having an issue purging a block from my drawing. Here are the steps I have taken:

-I first used the qselect command to select the block(s), there were 4 in the drawing.

-Then I erased all four of them

- I tried to purge the block but it was not showing up in the unreferenced block list.

- I went back into the qselect to find the block to see if there were any more, and the block did not even show up on the list

- I then tried to edit the block using bedit. After closing the block editor it told me that there were still 4 block references. This had me confused because I had already deleted the the four existing blockreferences from the drawing??

- I then tried to rename using the rename command and then attempt to delete it, and no luck.

I do not know what to do at this point, any help is appreicated.
