Lowrance 9 touch gen 2 Navioncs map

I have a Lowrance 9 touch Gen2. I have a navionics + card that I have been using for the 3rd year now. This past weekend I was at Lake Shelbyville. I noticed that the map depths were in meters instead of feet. Sonar was showing correct depth in feet but map was showing meters. When I turn OFF fish n chips then it would show feet. ????? When I switched to the insight map all was ok. I pulled up Kentucky lake and a couple of lakes I frequent in Wisconsin and the Mississippi River. They were all ok. Has anyone else seen this issue?
