I can't reproduce your issue, can you give more details about which system
you use, how you create the table, mnesia:info() if possible

3> mnesia:create_table(test).
{aborted,{badarg,test}}
4> mnesia:create_table(test,[]).
{atomic,ok}
5> mnesia:dirty_update_counter(test, all, 0).
0
6> mnesia:dirty_update_counter(test, all, 1).
1
7> mnesia:dirty_read(test, all).
[{test,all,1}]
