Inconsistent result possibly due to solve order

Hello,

I am trying to populate account "Acc1830" with the values of account "Acc1820" using below member formula written on "Acc1830".

"Acc1820"->"CP1"->"AC1"->"Total Custom3";

"Total Custom 3" is dynamic calc parent with custom solve order 60. "No Custom 3" is Store member shared under "Total Custom 3".,

I expect member formula should copy numbers from "Acc1820"→"No Custom 3" to "Acc1830"→"No Custom 3" and than "No Custom 3" should rollup to "Total Custom 3" but it does not seem to work.

Is there anything missing in this setup?

Thanks in advance!
