Hello Christian,
Could the problem be the different names for the field "Album_Images_Accross"?
WebProfile_de | WebProfile -> "Album_Images_Accross",
WebProfile_en | WebProfile -> "Album_Images_Accross_1".
This field is used in the "Album" for to calculate the table.
I haven't had the time to fully check all, but changing Album_Images_Accross to "@GetProfileField("WebProfile";"Album_Images_Accross_1")" on the album form fixed the problem for me.
And yes, a user would sign a template first, in this case I was a lazy user :-)
Best regards,
Jasper
