BUG: Institution: 0 is removed from the Exceptional costs field and an information message is displayed after a new offering is created

[astridSABC]

Describe the Bug
When an offering is created with "0" Exceptional costs, when you go back into the offering (edit), the "0" is removed from the exceptional cost field and an information message is displayed below the study costs.

Institution user would not know that their is an information message

Repeat for "Tuition", "Mandatory Fees", and "Book and Supplies"

Expected Behaviour
"0" in Exceptional cost field was saved
No information message is displayed

"0" in Tuition" cost field was saved
"0" in "Mandatory Fees" cost field was saved
"0" in "Book and Supplies" cost field was saved

Actual Behaviour
0 is removed from the Exceptional costs field and an information message is displayed below the study costs.

Adding a "0" back in the Exceptional costs field immediately clears the warning message.

Repeat for "Tuition", "Mandatory Fees", and "Book and Supplies"

Note: Adding a "1" or other numbers greater (>) than "0" (up to 999,999) does not provide the information message.
