[Jonathan Druart]

Have a look at the Koha log file, you should see the value of $value in it.

I search the archive online saw the advice to update the two fields<https://lists.katipo.co.nz/public/koha/2017-September/048966.html> (UPDATE items SET homebranch='LIB', holdingbranch='LIB'). I have done that and did the full reindex. But, that does not seem to have helped. Please advise.
