BSO member formula not working properly while ASO is working perfectly fine

In my Account dimension, I have four base members in which I would like to conduct the proper allocation.

For example, in my account titled 'Total Non-Reimbursable Positions', I would like to take the total positions (for example purposes, let's say 65,000) which can be allocated from the following entities:

Entity A - 30,000

Entity B - 12,000

Entity C - 8,000

Entity D - 5,000

Entity E - 5,500

Entity F - 4,500

and deduct them from the total Reimbursable (ex: 5,000), broken out as:

Ent. A - 1,500

Ent B - 1,000

Ent C - 800

Ent D - 700

Ent E - 600

Ent F - 400

My BSO formula is written as:
