[horde] Horde 6 RC5 CardDav sync issue with multiple emails

[Horst B Simon]

Hi,

I am have Horde6 RC5 with php8.4 installed and enabled in turbo’s backend.local.php homeEmail and workEmail for Contacts which have multiple Emails. When I have contacts which have 3 emails one in each field (email, home and work) it is synching correctly with the CardDav client, but if I have only one or two email addresses it fills all 3 fields and sometimes two addresses in one field. Are there any additional settings besides in backends.php which have to be changed, or has the CardDav sync app to be patched to correct this problem.
Further I noticed if you have a home address only it to synchronises the home street address to the work street address  field in addition to the home street address field.
