Error in solid element connectivity, the first 4 nodes must be unique

Hi, everyone

 

Thanks for reading this topic.

 

When I submitted a job, I got the error information:
*** Error 20222 (STR +222)

      in solid element connectivity, element 103338

      the first 4 nodes must be unique.

 

Then I find this element 103338 and check element, there is no problem with its connectivity and duplicates (see the bellowing picture). It is very confusing.

 

If I delete this element and translate + duplicate an adjacent one and then equivalence nodes, the error will still exist, but in another different element. I don't how many elements has this problem. 

I also tried renumber all, but it is still useless.

 

I really want to have your suggestions if you are familiar with it. Thanks a lot.
