Google assistant customize

hi guys,

this weekend i successfully set up google assistant (yay me) on hassio and added a few of my favourite channels, everything is working great expect when it comes to storing them in customize.yaml

if i store all my customizations in one file (ahhhh OCD!!!) and have my config file read
!include customize.yaml
everything is fine

when i move the customised elements of google assistant to a separate yaml file and point my config file to
!include_dir_merge_named ./customizations

they stopped showing up after i unlinked/relinked (i‘m waiting for the sync update in .58)

the thing its all my other customiszation .i.e icons ect work fine in separate files

could someone please help
