Marking a block and typing doesn't work

Description:

When I mark a whole block or more and want to type it doesn’t work. I have first to use the delete key to be able to write again. On a single block, it works when I just mark the text instead of the whole block. Is this normal?

To Reproduce:

    1. Mark minimum one block
    1. Try to type
