Contribuion approved but not visiable more than on the edit page

I made a release update on title/tt0273463 on September 15th (#250915-063042-065000) and it was approved yesterday, but it has not yet been visible on the main page (tt0273463/releaseinfo/?ref_=tt_dt_rdat), but if I go to the edit page the information is visible. How can this happen? I assumed that if an update is approved it should be visible on the main page, otherwise there is no idea to make updates. I have not always followed up my contributes as I have assumed that if they have been approved, they should be visible for all. Please explain what has gone wrong and what I should do to correct this. Br K-G
