I release dates , they then get blocked

[Laura1920]

I keep releasing dates for my Plus property, the website blocks them again a few minutes later. I’ve tried my computer, lap top, phone. Morning works. I losing potential bookings. I’ve tried messaging & calling support with no results. Is anyone else having this issue & any advise? 
thank you.
