Every version of 'Instruction of Hardjedef' I find appears to be text untranslated - any help?

So I was looking through some of the oldest known literature from Egypt and I've found something that's quite annoyed me, and that is that (as far as I can tell) there's a good portion of Instruction of Hardjedef (aka Instruction/Teaching of Djedefhor) that has just been... never translated? At least not easily searchable online.

First off, the longest version of text I could find online is by the Staatliches Museum (couldn't even find the exact translater...). I could find two other translations, but those were even shorter. Here's the link to Staatliches, if you want a look: https://smaek.de/en/news/lehre-des-hordjedef/

When trying to find the untranslated text to look through it I found this website: http://www.egyptomaniak.gr/Various%20Texts_N/Middle%20Kingdom%20Texts/MK%20Literature_N.html#Djedefhor

This untranslated text looked suspiciously longer then any of the versions of the poem I could find online. As yeah, checking the translation through google there was a lot of lines that appear to be just omitted!

It appears to be missing this portion:

ḥḥ.y n.k ḥm-kȝ ... sš.w r skȝ, r ḥȝm, r grg, m sȝw ḫpr rnpt nt šwȝt, wnm.n(.k) ỉr.r(t).f m ʿ.wy.fy grḥ ỉr.k n.k r wȝḥt rwḏw <pn> ḥm-kȝy n ỉs, st.sn n.k ḳbḥw mỉ s ỉḳr ỉmy-pr.f;

And everything after: sḫȝ n.k mỉ ḏd.t (st): mk nn wn(.w) ỉwʿ sḫȝ(w) n ḏt !

It should be noted - this is my first time getting a bit deeper into Egyptology and even bothering to check and compare the transliteration. I have no clue if this is completely normal and a ton of text doesn't have translations online, or maybe my source is completely bogus, etc. A little guidance would be amazing! I thought such an important and old text would have a lot of clear info online about it, but I'm not sure if I'm just looking in the wrong places but I quite like what I've read of this instructional and I'm looking for more information.
