Raymarine i70 won't do 3 box screen

[Redlegvzv]

The manual for the i70 says that it will do three-box screens for a Favorites screen that can contain digital data. In fact the illustration in the manual shows this.

It will allow a simple graphic item such as the depth guage item (looks kind of like a thermometer) to be placed in the box, but that is all it will allow.

My i70 will not allow any digital item to be placed in a 3 box screen. For example, it will not allow COG, Heading, and BTW to all be placed in each of three boxes. Works fine for the six box screen.

Is this a software glitch or am I missing something?
