I have a 2014 Catalina. When I left home the black and grey tanks showed empty. On arrival the black showed 1/3 tank. After 4 days usage the black shows 2/3 full and the grey still shows empty. Is the hopefully wrong tank level gauges normal.

BLACK - sounds normal. The location of the 1/3 light is at the very bottom of the tank and any water at all will turn it on (I call it my "not empty light").
Even a change in "levelness" can turn it on. After 4 days, having the 2/3 light on is also normal. It will turn on at about 1/2 tank and will stay on until the tank is about 7/8 full when the Full light will come on. (see photo)
The Gray tank.
Is the gray tank valve completely closed? Are you leaking water?
Here is a troubleshooting guide for the monitor and sensors.
DISPLAYS “E” ON ONE OR MORE TANKS BUT NOT ALL.
(A) VERIFY THAT LEVELS IN TANKS DO NOT MATCH DISPLAY.
(B) SWAP TANK CONNECTIONS ON PANEL (I.E., IF PROBLEM
IS IN “FRESH” BUT GREY IS GOOD, SWAP THE FRESH
WIRE “BLUE” WITH THE GREY TANK WIRE “GREY”. RESET
TANK FUNCTIONS TO SEE IF PROBLEM HAS ALSO
CHANGED TO ANOTHER TANK OR IS STILL IN SAME TANK.
(A) IF STEP (2) STILL DISPLAYS “E” ON THE SAME TANKS,
REPLACE PRINTED CIRCUIT BOARD.
(B) IF STEP (2) ABOVE DISPLAYS “E” ON DIFFERENT TANK
THEN THE PROBLEM IS AN OPEN CONNECTION IN THAT
TANK WIRING OR PIGTAIL, REPAIR OR REPLACE WIRING
