Blesta OTP QR code does not include Issuer

[CY.]

If a client enables 2-factor authentication in its Blesta account, Google Authenticator does not show Issuer information.

in blesta/app/views/client/bootstrap/client_main_edit.pdt

Below code 

<img id="two_factor_qr" src="//chart.googleapis.com/chart?chs=200x200&cht=qr&chl=<?php echo $this->Html->safe('otpauth://totp/' . urlencode($this->Html->ifSet($vars->username)) . '?secret=' . $this->Html->ifSet($vars->two_factor_key_base32) . '&issuer=' . $this->Html->ifSet($two_factor_issuer));?>" alt="" />

should be 

<img id="two_factor_qr" src="//chart.googleapis.com/chart?chs=200x200&cht=qr&chl=<?php echo urlencode('otpauth://totp/' . $this->Html->safe($this->Html->ifSet($vars->username)) . '?secret=' . $this->Html->ifSet($vars->two_factor_key_base32) . '&issuer=' .$this->Html->safe($this->Html->ifSet($two_factor_issuer)));?>" alt="" />

which encodes chs parameter correctly.
