unable to type Ip or Port: glitch.

When I enter the IP address, there is a glitch that stops me from deleting mistakes, so I have to start the page over. This is not a big deal, but the IP slot to type is blank. The Port slot is on default 19132, so when I hit delete, it simply wont let me. Nothing works to change the port, so I cannot play on any servers that have a different port than 19132. Because of this glitch, I cant play on most servers at all. It simply wont let me type over the existing numbers. I tried reseting, turning off, and deleting and redownloading the app. Nothing works. Please help, my friends have this problem too,
