Hi,

Very strange issue I am facing currently.

At a certain part of a job configuration (multibranch-pipeline job) the credentials drop-down list is empty for none-admin users, but not at every place where the drop-down list is used.

For normal users:

"Branch Sources" section: okay! drop-down list contains credentials (see good_01.PNG)
"Build Configuration" section: not okay! drop-down list is empty (see bad_01.PNG)

For admin users:

"Build Configuration" section: okay! drop-down list is contains credentials (see good_02.PNG)

I am not sure which plugin is responsible for this, to be honest. Here is a list of plugins with versions that I can think of being responsible for this:

Mercurial v2.11

Credentials Plugin v2.3.13

Remote Jenkinsfile Provider v1.11

We are using Matrix based security strategy (see authorization.PNG for details).
I've tried to enable all settings under 'Credentials' for none-admin users (the "jenkins-users" group), but made no difference, the drop-down list for the "Remote Jenkinsfile" section remained empty.

I've spend the last few hours searching the issue list to see if this is already reported somewhere. But haven't found and issue where at one place the drop-down list is filled and at another place it is empty.
