Dear CTX users,
After many months of procrastination and after discovering Ekdosis for LaTEX, I've dived back into the issues of different levels of footnotes in order to display on the first level the current notes and on the levels below the notes concerning lemmatization. Unfortunately, while I'm quite satisfied with the first page of notes, a strange phenomenon affects the lemmatization notes on the 4th page: the number of the line concerned by the lemma overwrites the last letter of the word in the lemma or in the previous lesson. I can't work out the cause of this problem. Even something like the addition of : \kern0.5em doesn't help.
Does anyone have an approach that I haven't intuited?

Below a MWE :
