conditionallay showin/hiding fields

I have following new problem:

multiple choice dropdown field and several fields selection that need to be hidden or shown.

The following matrix shows the dropdown options and in green the field that I want to be shown or in white hidden

for instance, if i setup the trigger event such as if "value in Mon to show  field tag_1 " and "if value not in Mon hide tag_1"

then it will hide tag_1 also when the selected dropdown option is i.e. MTW. If I do not set up the trigger "value not in..." then it does not work correctly

Is there as way to avoid this behaviour?

Thanks

Problem solved.
