Different slide gaskets on my slide

[Skipg]

Just noticed the slide gaskets on the front and rear of my slide are different. All other RV I have owned slide gaskets were the same. Is it a factory goof? Or is there some sort or a reason for the different styles of gaskets. My TT IS A 2020 Coachmen Spirit
Thanks for any input.

I have noticed that some have totally different mechanisims on different slides. Are yours the same other than the seals?
