Google analytics goals: wrong entrances and extits in funnel
===

I've setup a goal with this URL `(/compra/comprafinalizada|/pedido/presupuestofinalizado)` (match type: Regular Expression).

I've the following steps (there is no one required):

 1. /introduccion
 2. /filtros
 3. /pedido(/)?(index)?$
 4. /compra(/)?(index)?$

I'm having a few issues I can explain (I'm attaching an image with the samples):

 - A) Entrances from the previous step URL.
 - B) Exits to the URL of the same step they visits are going out from.
 - C) Exits to the URL of the next step.

What is going on?

I've been reading some information but it doesn't explain all my issues and, those it does, it says it's a reported issue but the posts are from 2010:

 - [Link 1][2]
 - [Link 2][3]
 - [Link 3][4]
