I am reading a journal and found a sentence which seems wrong. The sentence is,
It is apparent that the errors originate from outside the model.
This sentence used from and outside together which are supposed to be preposition here. I guess double preposition is not allowed in the English Grammar. May someone clarify this point for me? Moreover, I rewrote the sentence. May anyone check whether my modification makes the sentence correct?
The modified sentence:
1.) It is apparent that the errors originate outside the model.
2.) It is apparent that the errors originate from the outside of the model.
Any help are appreciated!

Follow-up question:
So double preposition is not incorrect. But in this example, it seems redundant to use "from outside". Like my 1st alternative, just "outside" is enough to express all the meaning. Should we avoid double preposition in this case? Or does it express some specific meaning that I have not understood yet?
