Calamares partitioner crashes when erasing LMV partitions - solved

I have installed Manjaro 18 on 3 different intel based PCs and it seemed that when selecting "erasing disk" option to remove previously installed partitions from distros with LVM the calamares built in partitioning module crashes and calamares with it. I did use another partitioning tool to erase those partitions prior to using calamares and everything did work like a breeze so no help needed.
