I'm glad a reset worked. The store visits that are currently avaliable are lani solo, lani/Marla (default if you aren't currently with lani), and a variation on the Lani solo visit that happend if you've seen the lani/Marla version and then unlocked the Lani solo version (sleeping with lani and having enough money for the date are the triggers).
The Marla solo and marla-after-lani versions are not currently in the game.
