In dropdown (and list) slicers the values are chopped off at whatever width the slicer is, showing "..." at the end. You can hover over a value to read the full text, but, this is not ideal when there are a large number of text values longer than the width of the slicer.
Under the Values section for Slicers, please add a setting for Text wrap and or Auto-size width of the text beyond the width of the slicer when you click the arrow to drop-down.
