Regex in the title not working

Hi there

I am trying to modify my title to exclude the following phrase.

10-K –

I have used the following on the Regex title.  However, it didn’t remove the phrase.  I am I doing something wrong?  I followed your YouTube tutorial and it didn’t work.
<table class=”responsive table cr_main_table_nowr”>
<tbody>
<tr>
<td>
<div><b>Run Regex On Title:</b></div></td>
<td><textarea class=”cr_width_full” name=”echo_rules_list[strip_by_regex_title][]” rows=”1″ placeholder=”regex”></textarea></td>
</tr>
<tr>
<td>
<div>
<div class=”bws_help_box bws_help_box_right dashicons dashicons-editor-help cr_align_middle”></div>
<b>Replace Title Matches From Regex: </b></div></td>
</tr>
</tbody>
