I created another game backup. I followed the V20 guide, and the flash Hinata in the Laundry room objective was successfully completed.So I cannot reproduce the problem you're experiencing.
I checked the conditions for those options completion through code of the game. One of the conditions is to complete path selection. But the code value of path selection, no matter whether you completed path selection, is always ‘false’ when judging whether the option is completed. Therefore the option can not be displayed as completed. I don't know if this is a bug or if it is related to future updates.
