Bug with number of product results

[luciaWOF]

Using Joomla! 1.7.3 and Virtuemart 2.0.0

In the products page, there's a field on the right hand side called "Results", which allows a user to define the number of products they see per page (All, 1, 2, 3, 4, 10, 20).  When you change this from the default ALL, you can't seem to change it back to ALL, you just get bumped back to the previous page. If you change it to say 2 you see the last 2 not the first two products. All a bit odd

As we've no plans for a big product catalog, it's been turned off in the theme for now with a bit of CSS, specifically
.orderby-displaynumber {display: none;}

Not sure if this has already been 'fixed' (I'm a beginner and user, not developer and first time using this forum )
