Hey again, I have a question about verb conjugation. I am learning about them, and I ran into something that confuses me so maybe you can help. I will use two examples here and let me know what you guys think.

I was told that with verbs ending in 〜る, that to conjugate for present/past tense, you remove the る and ad the た/て in its place, now here is my question...

I have seen 食べる conjugated like this, but it has always been as follows:
食べって or 食べった, ending with a った/って, not just a た/て. Same thing goes for sleeping, I have seen 寝って and 寝った, but not with the ta/te, always with the tta/tte.

I was wondering if there is any difference to these two methods and what they are! Thank you for your time.
