Bunpro stamp not showing up

Hi, I have completed upto Chapter 5 of Minno no Nihongo I track. My topics in Chapter 1 does not show the “Bunpro stamp”, rest all shows up with it. I have tried multiple times to complete it but still no luck.
OK, I have OCD and need this stamped, how do I do it ot admin can you mark it complete for me!!
Yikes, sounds silly but it is real for me !!
