Phone can boot into system, but defaults to TWRP recovery

The issue is that whenever I boot my phone up or restart, it goes into TWRP recovery, so I have to tap "Reboot", then "System" in order to boot to system. It can boot into system, it's just an inconvenience that it boots into recovery first and I would like to know how to fix this.
