I am using arcgis pro 2.8. I changed the text in attribute of shapefile using replace function in attribute table.(figure 1-2).


The replace worked perfectly without any problem. (Figure 3.) but when I save the edited feature, my table data was ruined. The unknown data overwrote the other row of data and it randomly wrote the other empty rows with changed text. (Figure4-5).



I checked with editable status already, this layer is editable. Any ideas what happen?
Thank you in advance.
