Innas set part mantra and grandeur

I stopped playing my monk over 10 years ago. I had several pieces of Innas grandeur. I recent just got some more pieces of the set but they are the mantra. Now im stuck with pieces from both sets. This causes the set abilities to not work. How do i fix this? Has anyone else seen this?

You need to find or gamble for more pieces of the current set, which is inna mantra. Run regular rifts, run greater rifts, use cube recipe #3 (upgrade rare item) on rare armor pieces where you are missing a set piece, and use the convert set item cube recipe to convert an existing duplicate inna mantra set piece to (ideally) a piece you do not currently have. Also spend your blood shards at kadala for missing set pieces.
