incompatibility with wp-wall plugin

It seems there are some problems with the wp-wall plugin available here: http://wordpress.org/extend/plugins/wp-wall/

see screen shot please: http://screencast.com/t/F33gpTmg
I am not using hte latest version of wp-wall since the author built-in a backlink without mentioning it in the change log.... using version 1.6 but I could upgrade to 1.7 and manually remove the link if that would work with the AVH plugin
