Applying Adjustments to Charges/Estimates using Manualpriceadjustments not working as expected

Summary:

When trying to apply adjustments to Charges/Estimates using /fscmRestApi/resources/11.13.18.05/manualPriceAdjustments REST service, it is adding adjustment record. I can view the adjustment record from UI, however the amount is not getting calculated. Do we have to call any other webservice to reflect the adjustment amount.

Content (required):

When adding adjustment from UI, no issues. If I add adjustment using webservice and then add another adjustment from UI, when I hit save, it is updating price for both adjustments. Looks like there is something else need to be done after calling the REST service, but nothing mentioned in the documentation.
