Using Initialized Array to filter against another custom array

[rnavrot]

My Flow intends to scrape 3 Master Plans every 15 minutes.

The aim is to transfer all the data from these 3 Plans onto a Master Excel table, where a 2nd Flow (yes, I will need help with that one too) will read the table, find the Planner Card information (title, due date, etc) and create a duplicate copy in every Sub-Plan.

We have 1 Sub-Plan for every account. There are ~100 Sub Plans.

I have successfully created a Flow which can read ONE of the Master Plans and update the table accordingly.

Next, I need to integrate the other 2 Master Plans into this table. 

In my head, I can simply make 2 copies of the logic that works for my ONE Flow. 

Though, I am having a hard time using the Filter results of my 3x Appended Array Variable.

...and these sections seem to append to my array fine. I think my issue is that this array does not have all the same extra fields as the straight-up Filter Body results.

The error happens here:

ALSO, my filter clearly filters out 0 results here, when there are about 50 entries in the table that it should be filtering against.

Please let me know if you have any ideas.
