Hi!
OK, I see. The problem with Webmaster Kit is actually a bug.
Anyway, if you want to get rid of add to cart buttons on grid/table views, then you should exclude the following templates from all view lists:
items_list/product/parts/list.button-add2cart.tpl
items_list/product/parts/common.button-add2cart.tpl
as described here:

Alternatively, you can replace the same templates with empty ones using Custom Skin module:

Please, let me know if it helps.
Tony.
