How does one keep a literal subscript from being translated into a indexed subscript?

Keyboard shortcuts work fine putting in the literal/index characters in Maple 2D.  If one converts the view to Maple 1D the text shown is correct.  But, as soon as one makes a next operation, Maple converts all of the literals to indexes!!!!  What's going on?

While it seems one could just keep working in Maple 1D input, this makes no sense.  The whole purpose...
