I have seen this sort of thing and invariably it was a product of using 
StandardForm, which
is not as stable as it should be - but not too surprising since it has 
to deal with a lot more ambiguity.
InputForm, on the other hand is rock-solid so I use it almost 
exclusively when writing packages.
I use StandardFrom for writing "pretty" notebooks containing simple 
expressions, for others to read.
To enforce use of InputForm you use the menu items Cell, Default Input 
  to override the default setting, which is likely StandardForm.
To convert existing StandardForm material to InputForm I don't like 
using the Cell, Convert To, menu items - I find
the resultant InputForm is not as readable as when I simply copy and 
paste into a new Cell (having previously set the Default Input Format 
to InputForm).
