Clonezilla part-to-part doesn't show sda2 as source

I needed to replace my 500G HDD with 256G SSD drive. 1. I shrunk the original partitions, 2. properly aligned SDD's partitions on 1 MiB (2048 sectors) 3. and in Parted Magic successfully transfered sda1 (old HDD) EXT4 boot partition to new sdc1 (SSD drive) using Clonezilla's part-to-part (direct disc to disc) transfer. **The problem: Clonezilla doesn't see my second partition on the old HDD - sda2**. This one is of 'extended' type and contains LVM2 PV. I cannot continue with my data transfer. Can anyone chip in with an advice on how to remedy this and - maybe- why this is happening?
