Creation of Kanban board resuls in error message

Our list of possible values for Priority has been changed according to company policy. The list contains only translated (in Dutch) values and none of the original (out-of-the-box) values.

When creating a new Kanban board in JIRA Agile, the board is created but an error is displayed:
"Swimlane <string>Expedite</strong> has been incorrectly configured."

It seems, according to Atlassian documentation, that the default JQL for a new Kanban board's swimlane definition is "Priority=Blocker".
However, the value "Blocker" no longer exists on our implementation of JIRA due to the aforementioned customization/translation.

It seems that the JQL the Kanban board's Swimlane definition is based upon a hard coded value for Priority, while the set of available values for Priotrity is customizable.
Instead, it would be prefered to not use hard coded values, since it cannot be guaranteed that these values exist. Better use a max. value or some way to determine the highest available value for Priority that is present.
