flexible fare - glitch?

[Wrldviewer]

I have flights booked on AA through EZair. When I check manage flights and look at the new pricing, the price has increased yet it shows my balance due as a $300 credit! I am afraid to click “continue” and lock in the new flight info in case Princess tells me it was just a glitch in the system and I actually owe an additional $106 based on the price of the new air fare. Has anyone seen this happen? The flight price increased yet the payment due shows a credit? BTW - I called Princess and they were unable to say what would happen if I clicked continue. I may get a refund or I may owe more money...

I checked mine and the total is showing the price as $4300 but the breakdown is 3x $3800. If I click through to take advantage of the glitch I lose my existing price of $6500. I didn't go through with it because I was afraid I'd lose my current price.
