The HP48sx has two set of flags in it.  The are flags that are used
internally by the calculator.  They are number -1 to -64.  The do such things
as for example, if -19 is set and you do a 2D the argument on the stack in
level 1 and 2 go into a complex number.  If flag -19 is clear they go into
a two dimensional vector.  Flags 1 to 64 are for the user.  The calculator
does not used them.  So in your case if you do a 3 CF then that three will
disapear.  For flags 1 to 5 (those are user flags since they are positive)
if they are set you will see the number of the flag at the top of the screen.
All of this is documented in the manual.  I took about 3 or 4 days to read
through the manual and found out lots of good stuff that will make my
life easier later.  How many people know what the %%HP T(3)... etc. is used
for in downloading programs?
