Bug: BPMN - User Task Filter is not working by Candidate Group

Dear JMIX Team,

We are working on a project with JMIX version 2.5 and we are using BPMN addon in our project, we just realized that the Candidate Group filter is not working in the User Tasks view inside the BPM menu in our project. Just to ensure this is not a problem in our application i created an example in the JMIX Demo Application Bookstore and the Candidate Group Filter is also not working there.

Below an example, William which is a Procurement Specialist has a task assigned.

When i open the User Task view with the admin role i can see the newly created task assigned to procurement.

But if i try to filter by Candidate group by “Procurement Specialist” and click apply, no results are shown.

As the BPM funcionality is really great, it would be very nice if this bug can be solved in futures releases.

Thank you
