How do you stop Lovable from making undesired changes?

My biggest frustration thus far is that when I try to change one specific thing... Lovable goes ahead and changes that one thing, amazing, and then changes whatever we were talking about like 2-3 prompts ago.

I've added this to my custom knowledge "Please follow only the instructions I have just provided. Do not look back in the chat and attempt to change anything other that what I have just asked. Please make sure to work slow and steady and ensure accuracy over speed. Please double check your work before finalizing everything is working. Please make sure everything you do is the best possible way to accomplish the task and is planned out and works as intended."

And it doesn't help much, maybe a little.

Is there any way to prevent Lovable from making changes that I didn't ask for from our previous interactions? We keep fixing things and then it goes and breaks it a prompt or two later.
