Fixed showing_x_admin_style_property_groups

[soloarquitectura]

showing_x_admin_style_property_groups

Is:
Showing {groups} admin style property groups.

Should be:
Showing {groups} admin style property groups

Without the final dot.
Because none of these phrases include it.

That template could be approached different, but I've made this change for consistency.
