Decimal spaces after ratio scale value

Hello,

I have encounter an issue and need some assistace. We use a format table for our drawings with information about the model. In the table there is a value for the scale: &scale[.3]. This value is followed by a parameter for the number of decimal places shown in the drawing. When using the ratio option for the scale, the [.3] keeps showing after the value. In the drawing you will see something like this: 1:1[.3] (see attached screenshot).

Is there a way to eliminate this? When using decimal and scale value it works fine, nothing is shown after the value.

Any help will be much appreciated.

Thank you.
