SEP debug - ILE COBOL issue

[dcpgm]

Hello,
I need help with debuging ILE COBOL programs using SEP. After the Debug Service is restart I can set Service Entry Point and call the program - debug works and everything lokks ok. But if I cancel the SEP, recompile the program and set the SEP again the program runs without opening the debug.
Probably the old program is still somewhere in the memory and the SEP is wainting for that.
Do you have any idea what could be wrong?
Thank you
