Greetings,

I'm webmaster for a site that rents bicycles (in DE/EN/ES with FaLang).
There are different bikes and every bike has different frame-sizes.
So I added the frame-size as supplement.

Now, after 2 years of running the site a customer told us, that it's impossible to book 2 bikes (same item) with different frame-sizes for the same period. And I'm quite sure that this worked in the past.
see attached files

the other thing is, that the total price on the booking site always shows in German, even if the same string is present in the en- and es-file (it's /language/xx/xx.com_booking.ini [TOTAL_PRICE] xx stands for language-code)
I prooved by changing the string in German language file and exactly this string showed also in EN and ES.

As I'm unable to edit the topic I write here:
can sent credentials to support by email on request

Update: "Preis/Tag" (means price per day) I had to translate in FaLang

Problem with booking of same article at same period (with different supplements):
When I enable "multiple reservations" in the backend configuration, I only can select one single day (from-to is gone) and it's not possible to press the "book it" button
