By default the Agile Tools & Filters will try to pre fill the project field in Basic view using boards JQL.

The reason for that is to limit the values of other comboboxes to the selected project.

In some scenarios that won't be possible:

• no project(s) specified in the boards JQL at all
• usage of OR statement for example: project in (A,B,C) or assignee in membersOf("jira-administrators")

In the given scenario pre-selecting projects A,B and C would exclude tasks specified by "assignee in membersOf("jira-administrators")"

A board using such JQL will be loaded without project pre-selection.

Additionally  the board administrator will be noticed about this on the Agile Tools & Filters Configuration screen.
