can't update dependencies via xml

[ahiya]

hello community

currently, I'm creating new groups and hosts using XML import.
all hosts are attached to preconfigured Templated (including items and triggers).
I'm trying to create the dependencies as well via the XML import, but with no success.
I'm keeping getting the below error:

Cannot update "description" for templated trigger "Unavailable by ICMP ping".

it seems that because I'm using templates I cant update the triggers.
is that correct?
can I work around it somehow?

below is my XML file.

my zabbix server ver -5.0.7
proxy ver - :5.0.10

appreciate any help\tips

thanks
