error on checkout proccess at userpoint.php

-- url of the page with the problem -- : on development
-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.7.0
-- PHP version -- : 7.1.4
-- Browser(s) name and version -- : any
-- Error-message(debug-mod must be tuned on) -- : Too few arguments to function plgHikashopUserpoints::onCheckoutStepDisplay(), 3 passed in /home/olfaaply/gp/libraries/joomla/event/event.php on line 70 and exactly 5 expected

Once I tested my localsite online with a PHP 7.1.4 powered server I found this error message:

Too few arguments to function plgHikashopUserpoints::onCheckoutStepDisplay(), 3 passed in /home/olfaaply/gp/libraries/joomla/event/event.php on line 70 and exactly 5 expected

public function onCheckoutStepDisplay($layoutName, &$html, &$view, $pos, $options) {

public function onCheckoutStepDisplay($layoutName, &$html, &$view, $pos=null, $options=null) {

Same here,

Testing my new servers (php7 instead of 5) and transfered a client with a backupsite.

Removing the legacy solved the issue, however some items (buttons f.e.) loose their layout so I need to fixed that in css. That's a little annoying cause this is an longrunning webshop, Everything is uptodate (joomla, Hikashop,etc).

And did you test in legacy with the patch provided by @PeterChain ?
