doubled offer

Hello. Challenging to see our two apartments twice on booking. One of them are just fine, already rated with correct prices and second ones are like new in booking with bad prices. Just afraid, if someone will book the wrong ones, what it will happened ? Cant probably service them ? This is just a bug or they should be done as a regular fraud listings? And why ? Can see it form app on two different phones as well as on two different computes, browsers logged or unlogged.  Thank you very much for help. Ondrej
