MARC Global problem with Delete Tags option

In MARC Global, when specifying a list of tags to be deleted, sometimes the first tag in the list would not be deleted.

For example, in the task below:

The first tag (520) would not be deleted unless it was entered as the 'TAG' value in a previously specified pattern (you would be able to know if that was the case because the option in the box below would not be grayed out).

This problem has been fixed in 233.

Note this problem would only apply when more than one tag was entered in the 'Tag' box.
