Transfer my earnings

Hi, I’m an affiliate for about 4 months. I made some sales and in the control panel says that I have achieved a profit of about 50 euros.

After 4 months I still have not received any money.

When trying to make a manual transfer I get the following error and I can not find the solution to solve it.

‘’ One or more validation errors have occurred:
Please, select a campaign ID. ‘’

Any solution?
Thank you
