This custom CSS would hide the -
separator, the To box, and the To handle of the slider:
.searchandfilter[data-sf-form-id="3918"] .sf-field-post-meta-EI .sf-meta-range-slider .sf-range-values-seperator,
.searchandfilter[data-sf-form-id="3918"] .sf-field-post-meta-EI .sf-meta-range-slider .sf-range-prefix:nth-child(4),
.searchandfilter[data-sf-form-id="3918"] .sf-field-post-meta-EI .sf-meta-range-slider label:nth-child(5),
.searchandfilter[data-sf-form-id="3918"] .sf-field-post-meta-EI .sf-meta-range-slider .meta-slider .noUi-base .noUi-origin:nth-child(3) {
display: none;
}
I think you might find it easier to use a new plugin we have for the layout and content of the posts. See this post:

Especially as you want only the title.
