I think I found a bug in v3.4 of GNU Parted.
This was my issue, put in removable media that had old Root and Home labelled partitions but they were mounted at /media/USER/xxxx. I wanted to format and i got an error about overlapping partitions.
I used sfdisk to check my sectors start and end.
I outputted the partition table data to a text file and edited the overlap as I did find one on /dev/sdb. I used sfdisk -d /dev/sdb > ~/Desktop/sdb-backup.txt
After editing this text file to fix the overlap as my sdb1 end overlapped my sdb2 start, i re fed the new partition data back in with
sfdisk /dev/sdb < ~/Desktop/sdb-backup.txt
After being confident i fixed the overlap that was causing Parteds GUI to not open and the partitions were resized after feeding new adjusted data sectors to the disks with sfdisk,
I got this print out when using a command: parted /dev/sdb unit s print to confirm the changes took place. My terminal spit this out
