Why won't my backspace, copy and paste work?

[Sales Account]

I need help. Here are the issues I'm currently having:

1. Backspacing - Trello won't let me backspace unless I highlight the letter or word I need to backspace. 

2. Copying - Trello used to let me highlight the words I wanted to copy without editing the description but now that won't work. It is making me edit the description then highlight the text to copy it.

3. Pasting - I will let me copy the text and paste it into google or gmail but it won't let me copy the title of a card and paste the title onto another board as the title. I don't want to copy the card because I don't need all of the attachments on the other board, I just need to copy and paste.

Can somebody please help? This has been incredibly frustrating, it started doing it this week.
