Booking end with a totaly wrong price for no reason

Today we got a booking email which show a booked Training but it show 899€ instead of 260€. While we thought about it the customer call us and report that he also got a vconformation mail for 899€ while he booked the Training for 260€ and a rental bike for 150€ and so he expect 410€ in total.
So we checked the experience and also the cost of the extra and both was fine. Then we did a test booking for the exact same Tour with extra and we got the right conformation.
This happend the very first time but it leave a strange feeling as we found no reason and even if the customer would have clicked the extra double or the training double, there is no way to get a result of 899 inner this experience. So my questions are:

Does this happen for some of you as well?
Does the Developer have any idea what could be the reason for this exotic mistake?
