Table which suffered corruption after deleting some rows

I was working on the attached table.
The cells in the  last column(under status) had the 'Wingding' character for lower case key 'R'(It looked like a checkbox, as is visible in front of text of column 3).
All the cells with headings (above the numbered cells in column 1 had character attributes: Bold, Centered.

I selected a number of rows, and deleted them.

After the deletion, the content of some cells was corrupted as follows:  
1. The cells in the  last column(under status) which had the 'Wingding' character, all changed to 'r'  (the font became Liberation Serif as shown in attachment).
2. All the cells with headings (above the numbered cells in column 1) that had character attributes: Bold, Centered, lost these attributes and became plain text.

This happened on several occasions when several rows of cells were deleted.
It became rather annoying to have text in multiple cells change, after deleting rows.
