I have the following issue

We rent bikes. The renter can also select which additional equipment he wants.
We offer:
Helmets
Batteries

the field helmets is a price field with a select list
The customer can select
Helmets --> no I dont want a helmet ---> 0 EUR
--> yes I want a helmet --> 0 EUR

Some customers want a helmet some cusomers don't want a helmet. That is why we make it selectable.

However in the rent request or buy request table it is not shown what the customer has selected. I guess the reason is because the price value is 0.
In the email which was send to us it is shown.

Hello. Fixed.
