Paragraph Field not saved in Brick (Update Brick is clicked).

As shown in the screenshots, I have a field called CTA Paragraph in my brick that references to a paragraph I had created(reusable paragraph used in other bricks too). Now while editing the brick if I click on Save & keep Published directly then the paragraph & all the other fields get saved correctly.

But if I click on Update Brick and then click on Save & keep Published it removes all values present in the Paragraph field.

NOTE: I added the patch from Prevent undefined index in bricks_preprocess_paragraph() it removed this notice but only saves partially.

Test Case 1: If no nothing is changed in the paragraph field the value remains even after clicking update brick & then save. (Works)

Test Case 2: If the added paragraph has multiple fields within it like my case(attached Screen Shot 2017-05-24 at 4.08.50 PM.png) then after adding this patch only the field which was changed within the paragraph is saved all the other fields in the paragraph becomes blank. Eg: Say my paragraph has 3 fields and I edited field_1 then field_1 is saved but field_2 & field_3 which had value initially gets empty. (Fails)

I am new to drupal (less than 2 months) therefore any suggestion or solution would be appreciated.
