something wrong with select and rejec parcicles in the user-friendly framework

Hi,
There are the following two events:
# Event number: 0
# number trig word
0 9170 0
# typ eta phi pt jmass ntrk btag had/em dummy dummy
1 2 0.855 1.862 158.28 0.11 1.0 6.0 158.0 0.0 0.0
2 2 0.445 1.008 59.83 0.11 -1.0 6.0 60.0 0.0 0.0

9 6 0.0 0.289 425.03 0.0 0.0 0.0 0.0 0.0 0.0

I input the synax:
reject ( mu ) PT < 56.0
select PT ( mu[2] ) > 10.0

The two events are still kept.

Inputting the synax:
select ( mu ) PT > 56.0
select PT ( mu[2] ) > 10.0
Aso the two events are still kept.

I do not understand the problem.

Many thanks.
