JS Validation Error with ACF Pro

When I try to enter a number into certain field in ACF pro I get an Error and it says "Please Enter a value less than or equal to zero" or depending on the number I enter "Please Enter a value greater than or equal to zero". The only number I can enter is zero. ACF Pro works perfectly with Marketpress deactivated. I will attach a screenshot below. I have also activated the support access on http://voip-phone.systems
