How to fix a spinner that does not show well on android

I have a problem with two spinners that are not shown correctly, in the interface, in the simulator the last two spinners are shown with a smaller font than the first one that says It's a Workshop, and testing in real devices in some cases the selected element is not even displayed in the two spinners of workshop type and workshop size, I hope you can give me suggestions as to why this may be happening. I leave the xml code of the activity and a screenshot:
