Datastore Admin Failure on Delete Consistently with Transaction Collision

[Nick44]

Consistent failure on delete.

When I am going to delete all our entities using the datastore admin tool, I am repeatedly running into the problem where all the entities are not deleted, and we get transaction collisions. Bellow are the errors I recieve:

Transaction collision. Retrying...
Transaction collision. Retrying...

I am not trying to do anything special, and am logged in as Admin for our Premier Account. Once this fails I then run it again and and again and eventually i get to the stage where there are just a few odd entities left. When I return to the Datastore viewer I can see our other Namespaces which have just a few entities at random within each.

I would be interested in what I am meant to do with this tool?

Cheers
