Tools won't allow subtraction in Numeric input expression

[ralfmaeder9001]

When trying to define the transformation of a tool with a numeric input, CAD Transform 2.0.6 misinterprets a minus symbol in an expression like for example "10-3" and puts erronously the minus symbol in front of the expression "-310". Blender 4.2.2, Windows 10 Pro, CAD Transform 2.0.6.
