Duplicate add-on ID found -> I am the owner of the duplicate

I made a dictionary as an add on, I then had to delete the add on, because I made it with a wrong locale.
I have now made a correct version of the dictionary, but I can’t submit it cause I get the following error:
“Duplicate add-on ID found”
I have read in the link below that some manual steps might be needed. Can any one help me out with this?


Thanks for your help
