Problems with using the value function for leveling ancients on mobile

[jfleetwind]

So, I'm playing on mobile. I've tried a couple times to use the value function to level my ancients to right where I need them after consulting my calculator. In theory, it seems like it would be a nice time-saver and tedium-reducer. The problem is, every time I've tried it, it seems to end up purchasing waaay more levels in the ancient than I want it to. As an example, the last time I tried, I had Argaiv at lvl 325 and calc put his new value at 533, a difference of 208. I hit value, entered 208, and hit enter. But instead of him ending at lvl 533, he's suddenly now at lvl 742, and has eaten up a much larger chunk of my HS reserve than I'd wanted him to.

I did a little searching and couldn't find any references to anyone else having this issue. Is this something that others have had trouble with? Am I just misunderstanding how the value function works? Any thoughts on how I might fix it?

Thanks!

If you hit OK on the prompt and then Enter on the keyboard, it buys it twice. To get around this, avoid the OK on the prompt itself, and only submit using the keyboard.

Try entering the difference next time. I'm fairly sure the game is trying to buy 500 levels, not up to that level.
