Unfortunately, we found a software bug in Version 3.4x and higher that happens when you are filtering multiple values and using the option Perform Match Filter in Mail & Deploy.
The error results in only one value being filtered.
As our Mail & Deploy Extensions for Qlik Sense make use of the option Perform Match Filter behind the scenes, this bug will affect the output from them.
Please note that only Version 3.4 and higher are affected.
The good news: The bug has already been squashed by our Mail & Deploy team.
Please install version 3.4.9.
Download version 3.4.9 from this link:
