Rollup Setting Value, Then Resetting it to N Immediately After

[pranavparakh7]

Hello James,

We have an object with multiple rollup fields (Contributions, Misc. Receipt, Total Expenses, etc). We have setup custom metadata for these rollup fields. One such field is Contributions (added image below)

After enabling field history tracking, we observed that these values are calculated once and set to blank/null immediately. In certain cases (Contributions) these are being recalculated multiple times. Please refer below.

Any help in identifying the root cause or directions to debug this would be really helpful.

Regards, Pranav
