That's just Lua. When you create a new table and assign it to that key, the previous table, despite being empty, still exists. It's just unobtainable, floating in memory, until it gets released by garbage collection. This has been a known issue for years. Blizzard relatively recently developed "table pools" where they reuse tables, even empty tables.

Instead of assigning a new empty table to an object that already has a table, use wipe() instead. If your desired effect is to just make sure the object is a table, use type() before assigning it a table.
