I'm not sure where the 3 dots are coming from if you are using the Toolset Product Image block to output the main product image and gallery.
I've tried playing around with the settings on my local site and I couldn't find any settings that would trigger that scenario.
You might want to try switching the Block Output setting from Toolset's Custom Output to the standard WooCommerce output, which will show the product image and gallery the same way as when not using Toolset to display products.
(The Toolset Product Image block is just a convenient wrapper for outputting WooCommerce's own product image gallery, though it allows you to customise it.)
