Error pre-loading RAM on MAX10

I'm trying to pre-load a 2-port RAM IP on a MAX10 10M08SAE144C8GES. It should support pre-loading since it is an SA version.

When I get to assembling I get this error in Quartus Prime:
Error (14703): Invalid internal configuration mode for design with pre-initialized eram

Googling led me to try this:
https://www.altera.com/support/suppo...02014_959.html
by adding
set_global_assignment -name ENABLE_ERAM_PRELOAD ON
to the qsf file.

But to no avail, as Quartus will not open the project with the line in the qsf file:
Error (125048): Error reading Quartus Prime Settings File C:/.../ADC_RAM.qsf, line 219
Info (125063): set_global_assignment -name ENABLE_ERAM_PRELOAD ON
