[RL] 12 & 13 Lakeview Apartments have visual bug in floor

In both of the Lakeview Apartments in Bellacorde of the Royalties & Legacies Expansion Pack world Ondarion, there are "walls" from the building details from the level below them visible through the floor in every section that has a walkway in the level below. They aren't as noticeable when the rooms are furnished, but they are still visible even through carpets. 

I first noticed this while building and playing in the new save I started to try out the pack, but then made a 2nd save to check that it wasn't something that happened while building, but it is there as soon as you load into the apartments.

Edit By crinrict: Added pack tag to title.
