It used to bother me until I really thought about it and asked myself "why?" - hey, if it makes them happy, go right ahead. I doubt anyone will be judged on whether they bow or genuflect, open their arms during the Our Father or keep them by their sides, etc., etc.
Snowing again here. Just to add to the 5 or 6 inches we got last night. *sigh*
Three genuflections are made during Mass by the priest celebrant: after the showing of the Eucharistic bread, after the showing of the chalice, and before communion. Special features to be observed in a concelebrated Mass are noted in their proper place (see nos. 210-252).
If there is a tabernacle with the Blessed Sacrament in the sanctuary, the priest, deacon and other ministers genuflect to it when they approach or leave the altar, but not during the celebration of Mass itself.
Otherwise, all who cross before the most Blessed Sacrament genuflect, unless they are involved in a procession.
Ministers who are carrying the processional cross or the candles bow their heads in place of a genuflection.

Again, that is genuflection for the Blessed Sacrament in the Tabernacle. And a bow for the altar.
