Resistance source during propeller design

When we select “I have a resistance curve” on the left pane, on the right side under Propeller/Propeller Design, the Resistance source still gives drop down for “Holtrop,…” as if we are estimating. Remove this.

The drop down is now removed when the “I have resistance curve is selected”. Until the two rows of data is entered, an information is displayed “No measured curve yet. Enter two points or more in the table on the left. Until then the propeller is designed against the Holtrop estimate, so the design below is provisional.”
