Hi,
Thank you for your interest in Essential XlsIO.
I tested the issue in v4.4 and 5.x versions and I am able to reproduce the issue in v4.4.0.51. But this issue is not reproduced in our latest versions (5.1 and 5.2). Could you please let us know which Syncfusion Essential Studio version you are using? Please test the issue in our latest version and let us know if the issue still exists. Our latest version is available for download from the below link.
