It will show as ??? if the IV would higher than 31 for the level, example: my Yanma at level 20, 31 speed and beneficial nature have 53 speed, when it levels up and you dont refresh the tab, it will show the stats of the next level, a level 21 Yanma would have 56 speed, which is impossible to a level 20 have. but if I have a Yanma with 10 Speed IVs instead, it will have only 49 speed at level 20 and 51 at level 21, which is possible to have at the level 21, then it will show like 29-30 speed or so, instead of ???
