Featured Slider Images – Title font issues

Hi, sorry to hassle again... Here is my web page link: https://www.mpo8.com/ When you look at the 4 images on the slider you will see a "DOT" in the middle. This is the only way to remove essentally all of the text from the TITLE FIELD for each image in the Featured Slider Section. Is there another way to do this? Also, if you wanted to change the font color for this or make a background which is transparent/graded how could I do this? Many thanks Michael
