Hello @marecg2
This may be because of a conflict with another plugin that uses the select2 library for dropdowns. Can you do a conflict test and see if the issue goes away? This doc explains how to do a conflict test if you are not sure: How to do a plugin/theme conflict test?
You should disable a plugin that influences the dropdown arrow icon styles or use custom CSS code to fix these styles. You can override the style by adding CSS code to the style.css file in the theme. You also can add CSS code to the field “Additional CSS” on wp-admin > Appearance > Customize > Additional CSS if your theme supports this feature.
Code example:
.um .um-search-filter .select2.select2-container .select2-selection .select2-selection__arrow,
.um .um-field .select2.select2-container .select2-selection .select2-selection__arrow {
display: inline-block !important;
font-size: 15px !important;
line-height: 35px !important;
text-align: center;
position: absolute;
right: 0;
top: 0;
height: 40px !important;
width: 34px !important;
}
