Moving Problem when changing Project, IssueType and Sub-IssueType

Issue Type Configuration

• Issue Type Scheme ITS_A with
  • Issue Type IT_A
  • SubTask IT_B
• Issue Type Scheme ITS_B with
  • Issue Type IT_C
  • SubTask IT_D

Project Settings

• Project A with Issue Type Scheme ITS_A
• Project B with Issue Type Scheme ITS_B

Issue to move
Project A contains :

• an Issue IA typed IT_A with a Sub-Task IB type IT_B

When I init a move of Issue IA from projet A to Project B, the Wizard ask :

• At step 1 : the target Project (here Project B) and then the Issue Type (here IT_C)
• At step 2 : the target status for Issue IA and sub-Task IB, but proposed status for sub-Task are issued from jira workflow and not the Workflow defined for the SubTask IT_D

Hopping that my explanation is correct.
