Dead sims are not greyed out in the relationship panel/Family tree

I have no mods and have never used them on this pc. Dead Sims on the family tree are no longer greyed out, no matter how many reloads, and it is through all of the save files not just one. Half of my sims who have died haven't turned into ghosts on the friendship tab, the friendship tab also does even acknowledge that the sim has died. When I went to check if I was mistaken it showed up on the family tree (not greyed out but said on the text). The ghost issue reverted sims that died before the bug started and it was random because a sim that died today turned into a ghost but the sims that died last night didn't (not game time, real time). Also the sim that died today ( a young adult mother with a child aged child) invited said child out to the spice festival. 

Thanks 

P.S the attachment shows the sim that died last night (Aicha) and the sim that died today (Yvette)
