ברכות לט,ב

It in SA O’CH 274,2 Friday night we cut the bottom chalah whereas in the morning, says the RMA there, we cut the top and the reason is kabala. Maybe, we can give a reason. We want to show that the morning when it comes to the meal, is more chashuv by cutting the top one than the night and by also using also the bigger chalah. Similarly, the sefardim who put tefilin on the hand sitting down, they want to show that the rosh is more chashev, so they stand up for it.

The covering of the lechem mishna has two reasons. For kiddush not to ashame the chalahs and by hamotzi to remember the mon which was covered.
