Sims 4 Doctor Career Sample Analysis BUG

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.49.65.1020
What expansions, game packs, and stuff packs do you have installed? All of them except Toddler Stuff and the Pet Stuff Pack.
Steps: How can we find the bug ourselves? In the Doctor career, using the Chemical Analyzer to analyze samples.
What happens when the bug occurs? Can't progress within the career since you can't analyze the samples from the patients.
What do you expect to see? I am having trouble with the Doctor career in Sims 4. I am at the point in which you are asked to obtain samples from patients and analyze them on the Chemical Analyzer in order to progress within the career.  My problem is, I can collect samples from patients, however when I click on the Chemical Analyzer, I choose the option to "Analyze Patient/Bio Sample", the list pops up with the samples I have in my Inventory, but they are all "greyed out" and cannot be selected. No matter how many times I click on them, nothing changes. It is as if they are not there. The patient samples I obtain are also ALWAYS stuck in my inventory, I can't drag them to a trash can or interact with them in any way. I can't even use them on the Chemical Analyzer, as I said. The only solution to get rid of them was to use the "Gift" option on another Sim and then gift them the sample so that I can get rid of them. Further, I also get a daily task to do "Lab Work" to test my skills by choosing the "Practice Analysis" on the Chemical Analyzer, but again this option never shows up for me. HOWEVER, if I do buy a Chemical Analyzer at my home lot, the option is there and I can use it just fine. It seems as if there is some sort of conflict with the Sample inside the Inventory that is not getting recognized by the Chemical Analyzer. Things I tried: Using testingcheats true, I did a Shift+Click on the Analyzers at work and used the Debug option. Didn't work. Using the free build cheat I deleted the Chemical Analyzers at work and replaced them with new ones. Didn't work. I tried resetting my Doctor sim with "simReset" in case this debugs their inventory. Didn't work. My game has a lot of CC. Turning them on/off didn't change anything. I remember in the past the Doctor career worked fine for me, and I didn't have this issue. Now I can no longer progress in the career due to that. Any help will be greatly appreciated!
