"Edit Sheet" option no longer an option when using RMB on drawing sheet?

Hi All,

This may be an off-the-wall question but I googled and got no hits on my issue.  All of a sudden, I no longer have the option to choose the "edit sheet" function within a drawing by right clicking on the blank area of sheet.  I had this option for years and it was convenient.  It no longer appears on dialog box.  Conversely, I still have this option on the left column where the sheets are displayed.  From there, I can still right click on the sheet and now have to choose "edit sheet" from there.  Strange thing is that once I'm done editing my title block, etc. I can now choose "edit sheet format" to get back into the drawing views.  Any ideas are appreciated!

no option when RMB outside of views area:

Can find from left column though:
