Loyalty module missing icons

[f.stas]

Hello,

 

I recently modified Loyalty.tpl to show order reference instead of order ID:

 

replaced <td class="history_link bold">{l s='#' mod='loyalty'}{$order.id|string_format:"%06d"}</td>

with <td class="history_link bold">{Order::getUniqReferenceOf($order.id)}</td>

 

(from https://www.prestashop.com/forums/topic/245382-solved-order-reference-in-my-loyalty/)

 

I edited tpl files both in domain/modules/loyalty and theme/mytheme (using specialdev213-bootstrap)/modules/loyalty.

 

Nothing changed at first, even thought I recompiled theme files and cleared cache several times.

 

 

However, today in my-account - loyalty page looks like this: 

 

 

 

For reference, my normal order history page looks like this: 

 

 

 

I already uninstalled and reinstalled loyalty module (which was a mistake as I lost its database tables , having to import it from backup) but nothing has changed.

 

Does anyone knows what could be a problem?
