Relax, this is fine. Most places are highly disorganized and inefficient in the inside. Sometimes they just look like that and with more experience you realize how things get done in means you didn't realize. In some cases maybe you have to brace for a year or two and moveon to a company that matches more closely your needs and expectations. I'm what is considered senior, I still do mistakes, product manager still does mistakes, CEO also does mistakes. That's fine as long as you do them only once and mitigate so they don't happen next time. Obviously some mistakes can require the employee to be fired, but in your case you seem to be eager to make things better so don't worry, you'll be fine and you are on a good path if you are asking those questions.
