Random often fails to return a result

I have a non-repeatable error that I wonder if someone can explain. I
am using Random to extract elements of three lists. The Table command
shows essentially how I do this. The output looks OK except sublist 9
has an element called List instead of returning a value. This
extraction error is occurring randomly. I have examined the three
lists to check if there are any "holes". There are no holes.

Thanks in advance for any advice!

Table[{starts[[Random[Integer, 100]]], investmentEnds[[Random[Integer,
100]]],
     investmentLevels[[Random[Integer, 100]]]}, {10} ]
