Confused about Trademark in Ad Content

[Two Bass Hit]

I am running an AdWords campaign which is uses the word "home" in the title (as in a house, or property that you would reside in). Several of my ads have been disapproved due to "Trademark in Ad Content". AdWords claims that the word "Home" is trademarked and I cannot use it in the title of my ads. I don't understand how you can trademark the word "Home". Am I missing something? Someone, please enlighten me!

Thanks

In case anyone is interested, I wrote team Adwords about this. They realized that an error was made and green lighted my ads in question.

That is pretty funny, as I am pretty sure home can't be trademarked.
