GParted dual boot expanding encrypted fedora disk

gparted live disks

/dev/sda3 is NTFS
/dev/sda6 is LUKS encrypted fedora btrfs

I want to move unallocated space from /dev/sda3 to /dev/sda6

/dev/sda3 (windows disk) has been resized and I want to use that unallocated space to expand /dev/sda6 (fedora encrypted) disk

Is this possible? Its allowing me to expand /dev/sda3 with unallocated space but not /dev/sda6

currently using gparted live
