Stacks in I2c display

Hello, been working on a weather project and got the lcd displaying the sensor values but on my Fahrenheit I’m getting columns of what I would call minus signs that are 4 high on each other. How can I get these off,
Thanks Ron

They are "User defined characters"

I suspect that you have said lcd.println("F") instead of lcd.print("F")

Yes I have but all is ok now,moved the cursor 3spaces past the "F" and it corrected it,

So you removed the "lcd.println" then?
