Dimensions in Metric

In Layout, I am suddenly unable to change the dimensions to Feet/Inches from Metric. Went into Preferences and changed it but it keeps defaulting to the Metric dimensions. Checked other Layout Projects and they also now won’t let me change from Metric to Imperial.

Dimension units are set in the Dimension Style panel either with the Dimension tool selected or existing dimensions selected.
