After installing Hikashop and importing items from Mijoshop no Add To Cart

-- HikaShop version -- : 4.2.3
-- Joomla version -- : 3.9.13
-- PHP version -- : 5.6.40
-- Browser(s) name and version -- : Chrome

I recently did a new install of Hikashop onto an existing system that has used Mijoshop for years. They seem to be abandoning it so moving to Hika as soon as possible. We imported all the items, categories, etc. and I set up a couple of demo menu items to see the layouts. They look fine except none of them have the add to cart buttons anywhere. I have read through several things on the forums saying stuff to turn on in the settings, etc. but none of them seem to work.

Hikashop button css in the config is set at hikabtn
front end cSS is set to OLD
styles for front end default
back end css default
extra css for add to cart is set to hikacart
wishlist buttons are set to hikawishlist

catalog mode is off

the items all have a large number of items in stock (digital downloads)

I also tried swapping the template of the site over to the default beez just to see if it was a template specific bug and even on the beez template the buttons would not show.

Any ideas?

I should mention that if I add a new product to the category on that one it shows up with the add to cart button... It is only showing up without it on the products that I imported from Mijoshop.

Awesome! TY but one question. I don't see Mass actions in the system menu. I went to the back end, Hikashop > Configuration > System but not finding a Mass actions item anywhere even when searching for mass in the various menus.

Edit- never mind. Now I see it. Wasn't waiting long enough for the system drop down. Thought it was in the tabs below somewhere. TY!
