Why can't I save text settings on the format tab? Receive error message "Value should be >0.1 and < 7"

When receiving the message "Value should be > 0.1 < 7" the system is telling you there is a setting already requiring the text to be larger than indicated. Look at your minimum font size in the "Force Fit" box on the Format tab. Note that even if you are not using the Force Fit command if there is a number entered in the minimum font size the system will force that size requirement. To resolve this you will either need to increase the font size selected or change the minimum font size in the Force Fit box.
