Incorrect Work Actions "Change business process and stage depending on field values"

The action does not work correctly with the standard Paid field. If you use additional field with the same data, then everything is correct, but this is inconvenient, because it is necessary at all stages and procedures for receiving payment to add the amount to the already paid, and the payment can be made manually. There are 2 actions at the stage Payment received, which indicate the transition of the process to the stage, depending on the Paid field. 1. Paid >0 2. Paid =0 In fact, if Paid > 0, then the process proceeds to the stages indicated in both the first and second steps. If Paid =0, then the process does not go to any stage. What is the problem with this field?
