Total receipts adverse variance

In below table, the question was to specify correct variance, whether adverse (A) or favourable (F). Below are the correct answers. Now my question is (which i don’t understand) why is total receipts variance adverse? compare to budgeted amount, actual receipt is more, as a result of more credit sale than budgeted, which should be favourable since we are having more receipts?

If you could please clarify. Thanks

Budgeted $ Actual $ Variance Value $ A/F
Receipts 46300 51800 5500 A
Payments 43000 49300 6300 A
Net Cash flow 3300 2500 800 A
