Please set both of the following project properties to false.
1- EnforcePascalCasingAlways When set to true, the setting MakeElementNamePascalCasing is always enforced. When set to false, the setting MakeElementNamePascalCasing is enforced only when names for new elements are created. Default is true. A new project inherits this value from the preferences.
2- MakeElementNamePascalCasing When set to true, all names of new entities, entity fields, typed views etc. will be properly PasCal cased. This means that each character in the name is lowercased, except the first character after each word boundary ('_' or ' ') and the first character. All spaces are always removed. When set to false, the name is left untouched, except for the first character, which will always be UpperCase. A new project inherits this value from the preferences.
