Zaps automatically shut down due to missing information, causing order processing issues

i do not understand why zaps automatically shut down when there is only partial information.  we process thousands of orders from various channels including quickbooks for example, which is another story. but not all orders from various platforms provide the same data in the same place always.  however, we still need the orders to populate in shipstation or they fall through the cracks.  but zapier sometimes seems like the tempermental angry trash collector who will not pick it up if everything is not in the right bin.  let’s just keep it moving. we can fix the order when the shipment is processed, but if it does not populate, it can easily fall through the cracks.  I don’t really understand the logic behind zapier processing 90% of them and then after a time deciding that its a problem and shutting off the zap.  this is also like paying a utility company for 20 years for power but then if your payment is off by 11-cents one time they shut off the power.  zapier should be a conduit, to help solve problems and keep things moving, not shut down if something seems out of line.  the whole world is out of line.  most problems are misunderstandings or language barriers including coding.
