Dahlia root rot question

I have grown dahlias for the past 3 years; however, this year I decided to buy 15 plants. I bought them from Eden Brothers as tubers. I’ve already had 2 break from what seems to be root rot, and I have two other from Lowe’s which snapped as well.

I always make sure I don’t overwater Because I know that’s a common cause. I just don’t understand what’s happening. If I need to send pictures, let me know.
