[URGENT] playlist time malfunction

[user-removed]

recently my spotify playlist time things (where it tells you how long a playlist is) is malfunctioning! this is only for my own playlists as others seem to be looking fine. 

for example: one of my playlists would say that 78 songs take about 4 hours while another having 62 songs says that it takes 78 HOURS + ADDITIONAL MINUTES??

attached is the problem for reference.
