Edit titles on Woocommerce Tabs Section with Kirki and/or Giga Store Advan

I can’t no more edit the titles like ‘sale products’ or ‘featured products’in the Wocommerce Tabs Sections with Kirki and a Giga-store theme (it is a child theme from Giga-Store). Before, I could edit the titles with a little sandwich (accordion) at the right of a block… Now I can only move the blocks or hide them (with the eye at the left of the block).
I’m not sure, but perhaps it is because I have translate the theme with Poedit, but I don’t think so, it works before and I am sure I had yet change the titles (I would like to change them again), it seem to be or a problem with the updates or with an extension ??
