Sideboxes not displaying

... Manufacturers show as Please select and the first two manufacturer's names - no drop-down.
...

In Admin > Configuration > Maximum Values > Manufacturers List - Scroll Box Size/Style

it says: Number of manufacturers names to be displayed in the scroll box window. Setting this to 1 or 0 will display a dropdown list.

Changing that should give you your dropdown.

Edit: that's on ZC v1.56c, I assume there's something similar in ZC v1.57b

Note that this is/was a setting that existed in ZC 1.5.1 which if that database had been imported and then upgraded through zc_install would have allowed the store to operate in the 1.5.7b version the same way that it had in 1.5.1... Otherwise, the site is truly being installed as a new site instead of one that has been set the way desired to support operation.

While I don't necessarily see the docs to have/show the link(s) I would have expected, but at least one functional link that at least explains a process through which to go to do an update which includes keeping the existing database not just pieces of it like was done above:
