Issue In Applying Business Process Flow On Existing Opportunities

Hello everyone,

This is Shahzeb, well we have implemented BPF on a project then got one requirement that connect old open opportunities with the process as well, those created without the BFP.

so i developed a small utility which creates a lead and fills data in it from existing opportunity then hook ups each other qualifyingopportunityid  into lead and orignatingleadid into opportunity and all other fields like stageid, processid, statuscode and state code, status of the lead is set as qualified and opportunity state and status to open, all things are settled perfectly and process flow is running as well but got some issues.

- if i wanted to go to qualify stage to see the lead it doesn't open it. like normal process flows lead is opened as clicked on qualify stage from any active stage.

- no textbox are being displayed on the qualify stage.

i tried to find out the reason but didn't get any, may be i have missed anything. please let me know if you guys have any idea.

here is a screenshot as well for reference

Thanks in advance.
