Recovering a lost cell in PGCedit

[Ghitulescu]

So, a long story short ...
I have a DVD that combined several languages in a single LU. I split them however in separate LUs, one for each language, and stripped several languages out (this is a documentary, thus it had 8 languages).

After a lot of editing (in the EN part), and cloning it to another LU, I noticed that I cannot get the original cells that were originally part of this other language.
PGCedit offers me the possibility of adding a blank cell, whose number, of course starts where the "invisible" ones end.

Therefore, while I cannot have a new number because they exist, I can not use them either since they do not exist.

Any solution? Other than starting all over?
