Another Monthly Elevator Maintenance Memo, why?

Another Monthly Elevator Maintenance Memo, why?

No changes since the last memo and before the last memo I can detect.

What are we to think given that one floor has the elevator lights with red on top and green on bottom after this second monthly maintenance? What are we to think when one elevator seems to hit a bump around the 33rd floor when going down?  What are we to think when arriving at the ground floor at least a couple of the elevators seem to be making up their minds as to whether or not to open?  What are we to think when a floor button is pushed then after stopping at another floor letting passengers off that light turns off and the elevator returns to the lobby?

"... our objective it to prevent /or minimize frequent elevators breakdowns that we are encountering now."  Who is "our"?  "Prevent /or minimize" "breakdowns"?  How about eliminate. "Encountering now"?  "Now"?  Has "now" been redefined?  How about encountering for years.
