Couple of technical php pieces to sort out on a wordpress site

I have the advanced custom fields setup on www.dgatours.com site and the alt tag is now showing on the images. I need the alt text to show on my custom fields.

Also I have installed Relevanssi Search plugin but it is only showing up one result on my search page. When you type london tours it should show up 5 or 6 pages but it just shows ones result.

Hopefully these are easy fixes for wordpress php expert.

Please let me know.
