Filter Override Issue in Roadmap Module

Summary: When a user creates a roadmap with specific filters applied, any subsequent filter changes made on the roadmap board override the filters initially set in Module > Roadmap Settings, causing unintended behavior.

Steps to Reproduce:

1. Set a filter in Roadmap Settings with the condition tag is not Mobile.

2. On the roadmap board, the user applies a new filter condition, e.g., tag is KO.

3. The new filter (tag is KO) overrides the initial filter (tag is not Mobile), altering the view of the roadmap.

Actual Result:

• The original filter (tag is not Mobile) is completely overridden by the new user-applied filter (tag is KO).

• Alternatively, the filters are combined with an unintended OR condition, displaying items that meet either tag is KO or tag is not Mobile, which defeats the purpose of the predefined roadmap view.

Expected Behavior:

• The filters set in Roadmap Settings should remain persistent.

• Any additional filters applied by the user should be combined in an AND condition, enhancing the current view without negating the original filter settings.

Impact: This issue disrupts the intended use of predefined roadmaps, leading to confusion and loss of custom configurations. Users are unable to maintain the specific roadmap views they initially set up, affecting their workflow and the reliability of the feature.
