Currently the implementation of Auto indent is that when a new line is created (such as when pressing the ENTER key) the new line should be at the same indentation level as the previous line.
If your problem is that when you create a new line it is not created at the same indentation level as the previous line then that is a bug. If you were hoping that the new line would be automatically indented another indentation level under the previous line, that is currently not the functionality. If the problem is the former then that is a bug that should be reported on Bugzilla, if the latter then you could submit an Enhancement request on Bugzilla as well.
As for the "indent size" setting, as you will notice that setting is under the "Formatting" group. Thus the setting refers to the type and size of the indents used when using the document formater on an HTML document.
