ModelSim - Intel FPGA Edition that comes with v16.1, v17.0 and v17.1 is not able to monitor signals related to fiftyfivenm_lcell_comb.
This is because the correct library is not loaded.

Therefore, as a workaround, add the following line to your script file to use the simulation library provided in the Quartus® Prime installation folder instead of the PreCompiled Library of ModelSim - Intel FPGA Edition.

This issue is resolved in ModelSim-Intel FPGA Edition, which ships with Quartus® Prime v18.0 and later.
