For Rent changing lot types to Generic all the time

Hi

I've gone to try and buy a residential rental as part of my game but every time I download a lot of the gallery the game is changing the lot type from Residential Rental to Generic and then refusing to accept I have a rental lot. I cannot then change the lot traits for each apparently/unit and the whole For Rent idea fails.

So if I by a lot, it comes up as Residential Rental, as a building downloads and places you see the individual units appear but once the game places the unit the lot becomes Generic and the rental fails and doesn't appear in the list of rentals in Live mode. Please look at the images which show the squence of the issue.

I've tried to repair my installation but that hasn't fixed it and I don't know what is causing it to fail as I do not use any Mods that link into the For Rent system. I've never encountered this issue before the Life and Death  update / pack (which bought along with Lovestruck at the time time) so assume something in one of these may be causing the issue?

Any ideas what the issue may be and how I can fix it as this is something I want to play with again but cannot at present :(
