I want config it as 298,257223563 so I type 298,257223563 in InverseFlattening Field (Tools -> manage datums ->The earth -> WGS84) and click "Save" but when I test (Tools -> manage datums ->The earth -> WGS84)again Nothing were change! please help me!

Me too!
I have the same problem with the inverse flattening for WGS84 value of: 298.257229164951

Hoang, did you ever got an answer from Franson?

In my case, nobody from Franson wants to answer this question! I was asked to register and ask the question on the forum instead of a straight answer like: Franson made a mistake and now we, the users, are getting in trouble with our partners, contractors, etc...
Bad choice to go for Franson in the first place!
