hypermesh与abaqus之间的导入问题

用hypermesh对一个二维结构分网后导入abaqus中，单元的类型为S4，我想将导入后的单元类型改为平面应力单元，在abaqus的keywords中改为cps4后以及截面属性后，计算总是出现

***ERROR: in keyword *CONFLICTS, file "Job-1.inp", line 24407: Keyword
*Conflicts is generated by Abaqus/CAE to highlight changes made via
the Keywords Editor that conflict with changes made subsequently via
the native GUI该怎么办，我是一个初学者，希望能够得到高人的指点，谢谢您。
