Rests in compound time . .

Some expert feedback on the notation of rests in compound meter?

I’m writing a polymetric pice in which all parts have the half note / minim in common, with piano and bassoon in simple time (4/2 and 3/2, respectively) and the bass in compound time (6/4).

The pick-up bar is to contain the equivalent of three half-note rests.

Dorico seemed to place the piano’s rests correctly (they represent one half of beat three followed by all of beat four).

However, for the bass’ compound meter (6/4), I would have expected the use of a dotted whole rest, to represent all of that part’s beat two, rather than breaking that beat up into two parts, via a whole + half rests:

I tried to affirm the bass’ compound meter by re-entering it (via the meter popover) as [3+3]/h – and [3+3]/h,3, for the popover – but that made no difference.

I also checked that I had selected the desired rest format for compound meter in Notation Options:

What am I doing wrong?

In the end, the only thing that gave me a dotted whole rest was to manually enter a dotted whole rest, using the ‘force duration’ tool:

. . . but is that dot really supposed to be in the space above the rest?

Thanks, in advance, for any help you care to share!
