mnesia delete calls on: disc_only_copies same storage size

[Benjamin Adams]

Hello,

I have problem where when I make delete calls to table disk usage 
doesn't decrease.

 > erlang:system_info(otp_release).
"19"
My Create Table:

mnesia:create_table(Tbl,
[
{type, set},
{attributes, [rowId, row1, row2, row3, createdOn]},
{disc_only_copies, [node()]}
]).
My Delete Call:
async_dyn_delete(Tbl, Results) ->
DELETE = fun() ->
lists:foreach(fun(Object) ->
{_, Key,_,_,_,_,_} = Object,
mnesia:delete(Tbl, Key, write)
end, Results)
end,
mnesia:sync_transaction(DELETE).



Storage on Disk for table is not changing with the deletes.

Do I delete differently???

Thank you,

Ben
