Hi StarEternal and welcome to Reaper!
If you could describe in more detail how Logic does this and what would be the result, you'd probably get help soon.
The ripple function can easily mess things up if you don't know what you're doing.
Might be the case that you can achieve what you want without using 'Ripple edit' at all.
Since I don't know what exactly you're up to I still can imagine you could try to make a time selection and choose 'Empty space at time selection' which would result in an empty space in the time selection by at the same time shifting all material inside the selection to the end of the selected range.
