Minimal-Variant price not updating

I am using the Minimal theme, which I believe has no support due to it’s age. I have searched older post and have not found a solution (that at least I can understand and implement). I see this seems to be a common issue, which is not great and not fair to the shopper.

Example: https://stockshowgear.com/products/cattle-livestock-trailer-safety-signs

I think I need add a snippet somewhere, but would like to see the exact thing needed and be directed to the exact place it needs to go - because I am only semi-smart in all of this! I am wondering if in the default Theme Settings-Products, I can change that first “From” line to something that include “variant” something.

I have checked with one app to see if they are the cause - Sezzle - they said no. Shopify at one time just told me to revert to an older version of my theme. That worked for another problem, but caused a different one.

Would appreciate any awesome help someone is kind enough to share.

Hi, I am trying to inspect the code on your store but I think you have disabled the right click option.

It will be easier for me to guide you if I can see your current theme product page template as well as its code.
