you might had more than one wallets in your old E_Tails and sent the missing transaction to one of them (already mentioned before)

That is exactly what it is! - at least I think so too.
Now, how to find that wallet - that is what I'm trying to find out from the community here!

apology for late respond.

I will answer all the questions in the next 48h

That was a very long 48hours.

.....the longest & most diversified I've ever experienced Shocked

So, are addresses of the restored wallets the same except for the missing one?
Refer to my last reply of in that thread:

Okay, how about the other addresses, are they the same as the addresses from your newly restored wallet?

If it's a no, your and this (1st paragraph) scenario is correct
If yes, it's most likely that old version bug or something else.

No, not at all. This are different addresses, entirely
