Strange error

Previously when I looked into contacts they were arranged in columns. Now they only appear in cards and I cannot find out how to change it so it becomes a list again.

Does anyone know how it is changed to list view?

This strange error came up when I by mistake added an encrypted string into the Quick add area. Then all columns disappeared and became cards instead. And there is no icon for changing it to list anywhere.
Sorry for asking a silly question.

problem solved without understanding why. I entered the system and all of a sudden the cards were gone.

It’s possible you hit a keyboard shortcut (t) that switches from table to list view. Not sure how many people are aware of them, but there are a few keyboard shortcuts for Mautic you can see by hitting the questions mark (?) key, shift-/.
