Implementation jobs lost parameters, defined in template job after restart Jenkins.

In template job defined next String parameters:
GITLAB_PROJECT = project
GITLAB_GROUP = group

In implementation job defined next String parameters:
GITLAB_PROJECT = someProject
GITLAB_GROUP = someGroup

Implementation job has checked setting: "Retain local job parameter values"

Its work as expected, bu after restart Jenkins, we see that implementation job lost all parameters.

And than we go to template job and without changes press save it (for sync parameters).
Then go to implementation jobs and enter again default values for this params =(
