OpenLayers Input & PostGIS Output Mismatch (Projection/Scale Handling Issue)

Before anything else, I would like to say thanks for this great geo-Drupal distribution.

After some reading & tinkering, I've successfully configured Cartaro to work with these setup:
1.) XAMPP 1.8.1 (Apache 2.4.3, PHP 5.4.7) + Cartaro (beta2) + OpenGeo Suite 3 CE (PostgreSQL 9.1, PostGIS 2.0, GeoServer 2.2)
2.) WAPP 5.3.17 (Apache 2.2.23, PHP 5.3.17, PostgreSQL 9.1.5, PostGIS 1.5.5) + Cartaro (beta2) + GeoServer 2.2

I've tried also both with and without the "Support GeoServer Drupal authentication" option at the last stage of installation, and the Cartaro 7.x-1.x-dev version and they've all worked like a charm; after that, I've added some modules (Geofield, Leaflet, etc) & content types with spatial attributes. In all of my setups, there's one common problem though: the plotted output or layer extent of the point/line/polygon features from the input OpenLayers map is scaled differently or has different map units, or too small with respect to the base map, or perhaps transformed automatically to a different projection. Kindly see the detailed attached screenshots. I hope someone could shed some light regarding this matter. :)
