SniperPrettyPrinter - Abstract keyword getting deleted

When using SniperPrettyPrinter, for the below input the expected output is not generated. Transformation is working as expected but abstract keyword is getting deleted from another method of the same class.

Input :
`public @interface CtAnnotationMethodProcessor {
String totals();
abstract String subjectName() default "CSE";
}`

Expected :
`public @interface CtAnnotationMethodProcessor {
int totals();
abstract String subjectName() default "CSE";
}`

Actual :
`public @interface CtAnnotationMethodProcessor {
String totals();
String subjectName() default "CSE";
}`

Spoon print config :
launcher.getEnvironment().setPrettyPrinterCreator(() -> new SniperJavaPrettyPrinter(launcher.getEnvironment()));

Spoon version : 9.1.0-beta-10
