git合并分支,已经解决了所有冲突,仍然报错Merged branch '*' with conflicts: Unresolved conflicts remain in the project

在idea上合并两个分支,在手动解决所有分支之后,仍然报错Merged branch ' * ' with conflicts: Unresolved conflicts remain in the project .Resolve now.
用git status命令查看,所有的文件都是committed,点击Resolve now也是什么都没有,右下角的图标是Merging'' * ",有大佬解惑一下吗
