engine analysis not showing up when using custom position

I like to play custom positions against bots, however when I choose “custom position” the engine analysis doesn’t show, specifically the feature were it tells you how my move is rated compared to the best move (excellent, best, good, blunder, inaccuracy). Starting from a normal position it does show up using the same settings.

Using the IOS app on iPhone

Is this a known bug?
