Hi,
Regarding your questions:
1. On the module General Settings tab "Count" option was set to "1", so only one image was displayed
2. You can change it on the Slideshow Settings tab (slide duration and transition speed are defined in milliseconds)
3. It looks like empty text container, try to add the following custom css code to remove it:
.slideshowstandard .slidecount, .slideshowstandard .allitems {
display: none;
}
Cheers
Joshua
