H1B transfer:any problem for 2 transfers in a month?

I am transferring my H1B to company A and just got a receipt last week.

Now I got a new offer from company B and decide to go.
So a new transfer will be filed in 10 days from now.

I have not got a paycheck from company A since they cut check monthly.

I am wondering is there any problem?
Do I have to withdraw the first one after the second transfer is filed?
