Why won't my Microsoft Word program let me replace selected text?

My Microsoft Word program does not allow me to manipulate text. For example,
when I select a word or phrase in order to replace it with more text or to
delete it, the cursor moves to the beginning of the word or phrase after I
press a letter or the delete or backspace keys. I have to backspace or delete
each character individually to replace the text. How do I stop the program
from doing this? It originally worked normally.
