The display of parameters seems to be reproducibly inhibited after  
backspacing  or selecting and deleting a function name that had an  
argument list displayed. If I type "duplicated(", and then see an  
argument list , then backspace over it and hit <enter> and then type  
"duplicated(" again,  I see no arguments. I did discover by accident  
that I sometimes get back the desired behavior after typing  
sessionInfo(). I will generally get display of arguments from other  
functions after that, but "duplicated" seems to be blanked out until  
<something happens to make it recognized again>.
