Parsing 无法设置优先级规则以强制Jison中的移位

我正在尝试用我的语言实现一个功能，在这个功能中，您可以通过执行

return someVal然后someCode（）

在函数中返回后执行语句

我对返回语句有以下语法：

ReturnStatement:
    'RETURN'                                                { $$ = new yy.ReturnStatement(null).pos(@$)}
|   'RETURN' Expression                                     { $$ = new yy.ReturnStatement($2).pos(@$)}
|   'RETURN' Expression 'THEN' Statement  %prec 'AFTER'     { $$ = new yy.ReturnStatement($2, $4).pos(@$)}
;

在Jison文件的标题中，我有以下优先规则：

%nonassoc 'NAME'

%right ':'

%nonassoc 'IF' 
%nonassoc 'ENDLN'
%nonassoc 'ELSE'
%nonassoc 'DEF'

%right 'ASSIGN' ''
%left 'YIELD'
%left 'OR'
%left 'AND'
%left '==' '!=' '<' '>' '<=' '>='
%left '+' '-' '&'
%left '*' '//' '%' '/'
%right 'UMIN' 'UPLUS'
%left '^'
%left 'AWAIT'
%right 'TYPEOF'
%right 'UB_FUNC' 'B_FUNC'

%left 'ACCESS'

%nonassoc 'INDEX_LEFT' 'INDEX_RIGHT'

%left 'CALL_LEFT' 'CALL_RIGHT'

%right 'NEW'

%nonassoc 'AFTER'

%%

%nonassoc“名称”
%对'：'
%非ASSOC“如果”
%非ASSOC“ENDLN”
%非assoc“ELSE”
%非ASSOC“DEF”
%右键“分配”
%左“收益率”
%左‘或’
%左‘和’
%左'=''！='''''''''''='''
%左“+”-“&”
%左'*''/'%'''/'
%右“UMIN”“UPLUS”
%左“^”
%左“等待”
%右“TYPEOF”
%右“UB_FUNC”“B_FUNC”
%左“访问”
%非ASSOC“索引左”“索引右”
%左键“左键”左键“右键”
%右‘新’
%非ASSOC“之后”
%%

我知道，当存在冲突时，Jison将默认转换，但我希望设置优先级规则，这样我就不会在Jison中收到shift/REDUCT冲突警告。我认为将最后一条规则置于所有其他规则之上可以做到这一点，但我得到的却是：
