Help with recall/loading MIDI Loops into Seq~ (via Pattrstorage & Dict).

Hi C74 World. I'm making a 6 track MIDI looper to use (multiple times) in Ableton; most of the device is working properly but having some problems with recalling & loading MIDI sequences into the Seq~ object from Pattrstorage. I'm sending the Seq~ info to Dict/Pattr to then be saved into Pattrstorage as dictionary.

I would like to save Seq~ info as a preset and be able to have any previous saved Seq~ data (& dial positions) autoload from Pattrstorage via Dict back to Seq~ upon reloading the Ableton set. I can see in my testing that the info in Dict (blob) is being saved into Pattrstorage.

PROBLEM: Pattrstorage is not always consistent in recalling/loading the correct data when swapping between presets or when Ableton loads. Sometimes when I load the set in Ableton the Seq~ info appears in Dict and I can send it back into the Seq~ object and play back the MIDI. Then when I change presets the info in the Dict disappears or other times I change presets and not all the info is there in Dict e.g. only 1 of 3 tracks, to send back into Seq~.

Not sure if:
-the Pattrstorage, Autopattr, Dict/Pattr settings are correct?
-have I not connected things in the right order?
-is something else that I've completely missed?

I've got both the M4L device and the Max patch below. Thanks in advance for any help.
Cheers Joel.
