Reply To: htmlMails: please add [resource-name]

Please use the edit function, hard to answer everything.
If a guest makes a reservations there’s no resources number selected. You have to define it at approvement or edit. If there’s a zero at the table it means that none is selected, even through it defaults to the first in the select.

For the email that sounds quite weird. Please copy the line from both templates here, even if they are the same. Will look into reproducing it
Regards
