Note that LiveCode makes no distinction between an object having a custom 
property with an empty string, and an object that doesn't have that custom 
property.

If you ask for the uIjustMadeItUp of any object, the value will be the same 
empty string as it would be if there was a custom property of that name. 
(There is a way of testing whether the custom property actually exists, but 
it's convoluted.)

So like Thierry I suspect the problem is that you have five checkboxes - which 
might be on one card or five cards - that have no uMyLabel property or a 
uMyLabel property with empty value.

Thierry's script suggestion had the problem that it will only show you the 
last found one (because each "put" overwrites the previous).  So if you want 
to find them - ie if you don't think you should have any - then you could make 
this variation, to just collect the card and button info for checkboxes that 
either don't have the uMyLabel property, or have it empty:

              if  the uMyLabel of button n of card y of stack "MyStack" is 
empty then
                put y &&  n & cr after theList
              end if
    -- temporarily suppress normal data collection
    --      put the uMyLabel of button n of card y of stack "MyStack" iinto tName
    --     put tName & cr after theList

On the other hand if you don't care about that, then just add another test so 
that you don't collect the ones where it's empty:

             put the uMyLabel of button n of card y of stack "MyStack" into tName
             if tName <> empty then
               put tName & cr after theList
             end if
