The problem is with this kind of items in which the description end with a code of two letters, one or more numbers, and the full stop (e. g. LU7, SG8 and IP22). However the item Q29505587 didn't get an error:

Result

Q29505587       en-desc full stop removed

The difference between this item and the last three I reported here is the number of letters and numbers, in this case there is only one letter (A483).
