Thanks Elliot,
I did a clean install and everything seems to be working now. Please help me with only one thing.
I replaced radio buttons to check boxes from ACF, resulting, I can choose more than one bedroom for a house.
For example, I have
House 1 : Checkbox 1 selected
House 2 : Checkbox 2 selected
House 3 : Checkbox 3 and checkbox 1 selected
Now form archive page, when I select checkbox 1, I only see House 1, where I should be getting House 3 as well.
Could you be kind enough to tell me where/what to add/replace the code?
Thanks
