Showing direction arrows on hierarchical data

I have a set of data with a custom hierarchy (anonymised sample below

 

What I need to be able to do is display the data in a grid with a final column that shows the upward or downward movement at each level, with level 1 being the highest and being a sum of the levels below

I have a calculated column showing the difference between this week and last week and another one with this formula

 

↕ = SWITCH(
    TRUE,
    Main[Change]=0," ",
    Main[Change]<0,UNICHAR(129095),
    Main[Change]>0,UNIChar(129093))
 
which I found on another site.
 
The trouble is, it doesn't work, mainly I think because using a matrix, this new column is always forced to 'summarize' and with it being a string it defaults to 'first' (first of what though, and in what order).  It tends to show only onw arrow (the down arrow) and sometimes shows blanks when clearly there isn't a change.  Obviously doing something wrong but having trouble understanding the logic.

PS I tried this too

↕ = SWITCH(
    TRUE,
    Sum(Main[Change])=0," ",
    Sum(Main[Change])<0,UNICHAR(129095),
    Sum(Main[Change])>0,UNIChar(129093))

PPS the CF I created to colour the arrows red or green seems to work fine so I'm thinking it's the 'first' summarization that's causing the problem
