spans are being added in the

I am using a gallery plugin (not the one included in the Enfold theme), and it is acting very erratically. I contacted the plugin support folks, and they have pinpointed an area within the Enfold theme code where they say is the problem. The following is my correspondence with them and there reply:

Ron,
Please, be informed that our developers have gone through the issue.
Here is their feedback:
The issue is coming from the theme, not from the plugin. Please see the attached screenshot. The spans are being added in the . Could you please, contact the support team of the theme that you are using? So that they fix the issue not to have spans in the ?
