Hi @Mr Busy,
Add the following JavaScript code into a Script Editor web part in Edit list item form page(http://xx/Lists/xx/EditForm.aspx).
<script src="http://code.jquery.com/jquery-3.1.0.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function(){
var button = $("input[id$='SaveItem']");
button.removeAttr("onclick");
button.val("Apply");
button.click(function() {
var elementName = $(this).attr("name");
var aspForm = $("form[id='aspnetForm']");
var oldPostbackUrl = aspForm.get(0).action;
var currentSourceValue = GetUrlKeyValue("Source", true, oldPostbackUrl);
var newPostbackUrl = oldPostbackUrl.replace(currentSourceValue, encodeURIComponent(window.location.href));
if (!PreSaveItem()) return false;
WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(elementName, "", true, "", newPostbackUrl, false, true));
});
});
</script>
