Thumbnail Display Issue After WoodMart Theme Update

Hello,

Today I unintentionally updated my WoodMart theme. This happened after I clicked on the “New update available” button. My intention was only to read about this update, but it started updating automatically. As a result, my files were overwritten to default, such as header.php and other pages. My Loco Translate translations are also all gone. No, I didn’t have a backup.

Therefore, question 1:
Is it possible to retrieve the lost translations and codes somewhere?

Question 2:
The single product page thumbnails look different on desktop than on mobile. I achieve this through Options presets within the Theme Settings. Please see the image below:

On desktop, everything works fine after the update, the thumbnails are displayed large and wide, stacked vertically. See the desktop settings below:

The thumbnails are set differently in the mobile preset. See the mobile settings below:

After the update, the small thumbnails under the main product image are no longer displayed (mobile device), instead, there are dots. That is not intended. How can I bring back the small thumbnail images? Please refer to the attached image for reference:

Disabling plugins did not help. When refreshing the mobile page, I notice that all the images load and appear very quickly, but then they disappear. Perhaps something is blocking it now? I hope you can assist me with this.

Thank you in advance.
