wrong indenting on erb/rhtml files

<div>
..<%- if true -%>
....true
..|  
</div>

in the above example, pipe (|) indicates my cursor position, and I have a shortcut / live template (r + tab) to create the <%- -%>
whenever I use the shortcut to create closing end

<div>
..<%- if true -%>
....true
....<%- end -%>
</div>

it always end up that way, with the end indented incorrectly. is this just my configuration or some known bug?
FYI, I'm using 4.0.2
