Need help understanding the xp 20% bonus

[Minkey]

Hello. I used the wishing well on the map which grants me and extra 20% xp for two days. However, when I used an Emma on the map, I was only awarded the 2000xp she offered and not the extra 20%.

When does the 20% bonus apply?

Thank you,

Minkey

It doesn't apply to the valley map Minkey.
