Change base id and Node id removes decimal points

I have 4 emonpi’s I want to post to a single account. I understand in order to do this I must change the node id (base id) in the interfacers section and the node decoder in the nodes section. the default value on all the emonpi’s was 5 and when I changed the node id and node decoder value to 4,3, or 2, the value displayed VRMS and temperature without a decimal point. for example if node id and decoder value was 5, 125.50V and 23.8C is displayed. With node id and decoder value at 4,3, or 2, 12550V and 238C is displayed on the LCD.

What happened to the decimal point when i change the node id and decoder value? am i missing a step?
