When adding a Search the Channel label is set the same as the Search label

Problem/Motivation

When editing a channel (for example admin/config/services/entity_share/channel/abc/edit). and then adding a new search, the label of the added search replaces the label of the channel.

Steps to reproduce

Browse to add a channel: admin/config/services/entity_share/channel/add
Enter label "New Channel label"
Select Entity type "Content"
Select Bundle "Basic Page"
scroll to the bottom and click "Save"

Edit the newly created channel: admin/config/services/entity_share/channel/new_channel_label/edit
Observe the channel label is "New Channel label"
Click on the "Add a new search" button
Enter "status" for Path
Enter "New sort" for Label
Click "Save"

You will now be back at the Channel edit screen. Observe that the Channel title has now become the title of the new search you just added.

Proposed resolution

This is caused by both fields having the same form element id "edit-label".
in SearchAddForm.php change line 38 from

$form['label' = [

to

$form['search_label'] = [

fixes this issue. I guess the same would apply in SearchEditForm.php
