I have Parallels 20.2.2 running on MacOS 15.4 and no option for Rosetta w/ Linux

I have parallels 20.2.2 running on MacOS 15.4 and I am not seeing options for installing Linux VMs with Rosetta. I don't see Ubuntu Linux with Rosetta in the Create New page and I don't see Rosetta as an option on the CPU & Memory configuration page for the Ubuntu 24.04 ARM64 VM I installed. I have confirmed that Rosetta has a process ID in MacOS, so I know it is installed. This is the only reason I purchased Parallels, so I am a bit disappointed. Any assistance would be greatly appreciated.
