Rest in part for empty pickup bar

See my two screenshots. My pickup bar is a 1/8 bar with the time sig hidden. In the score the rest appears as I want it; in the part it appears as whole note rest. Unhiding the 1/8 time sig doesn’t change anything. Any suggestions from anyone? Thanks!

It is probably possible to fix, but if it is an option here to use the native pickup bar functionality, you could set the time sig to 5/4,0.5 and hide it if you don’t want it to be seen. That might be more efficient.

Beautiful—worked perfectly. Thanks!
