check your settings in the toolbox / vector charts.
display category "mariners charts" and "select all" on the left.
uncheck "important text only" and try "declutter text" on and off
.....and full database rebuild in "charts"
You might also want to go to Tools>Chart>Vector charts. In the lower right hand corner is a slider bar for CM93 chart detail. Try moving that toward the +5 mark. It changes the amount of information shown in the display.
