Boot switch Polo vivo 2010

[Hugos]

Good day

I have a Polo Vivo 1.4 2010 model.

My boot does not want to open when I press the botton on the boot itself, but it opens when you press the button on the remote, or if you use the key and open it manually. If you press the unlock button inside the car you cannot open it without switching of the car and pressing the button on the remote. what can I do to fix this problem.

Kind regards

Its a Sedan, not a 5 door.
