Same calls with different results

[oliujunk]

node: v10.16.0, casbin: v3.0.3
Policies are stored in mysql, first call console.log(await enforcer.getUsersForRole('consumer')), return [ 'YFKJ187244601', 'test' ], second call console.log(await enforcer.getUsersForRole('consumer')), return [ 'YFKJ187244601', 'test', '7792707', 'bjdxt' ], .....It's different every time.
I am also try to store policies in redis, the test result are same.
The policies about 40 items.

Works well when I use node-casbin v2.0.4
