size image missing

[SailingpointFed]

Hi, 

We use the Theme impulse and we occur on the problem of not having defined sizes on images.

here is the section:

<img loading=lazy class="lazyload"
data-src="{{ img_url }}"
data-widths="[360, 540, 720, 900, 1080, 1600]"
data-aspectratio="{{ block.settings.image.aspect_ratio }}"
data-sizes="auto"
alt="{{ block.settings.image.alt }}">

Many t
