multiple services in the same order

Good morning,

we have a problem with the selection of services:

step 1) I add 5 tickets for “space zone +5anni”. so far everything ok.

step 2) if I want to add for example 9 tickets for the “space zone Adulto” service you can notice that the service is not added or the number of the previous service is also updated!

How can we fix it?

Thank you!
