line separator indentation issue

[yoo 0]

In Evernote 5.8, it is easy to indent line separators, so as to achieve effects like this

 

 

But in the later versions of Evernote (e.g. 6.1.1), if you repeat the same procedure (either (i) click tab to indent, then click the line-separator button to insert line separators, or (ii) insert a line-separator, then (ii) click tab to indent),  you get something like this

 

Basically, line separators by default spans the entire note, and there's no obvious way to apply indentations to them. 

This has messed up a lot of notes I've stored in the old format. Would it be possible to fix this bug?
