Modify Titles and summary of imported Articles

I used the native XML import option to bring a complete number, but when I tried to modify the summary and title data, they told me that there was an error and blocked the save option.
How could I modify this data?

What I tried to resolve the issue:

Application Version - e.g., OJS 3.3.0.5
