Configurable product not showing all associated products in front end. Magento 2.1.2

Question

I have a configurable product with 6 simple products associated. The configurable product has 2 options, color and size. Color is set as black option, with size being selectable.

I have checked as many of the suggestions and all of my settings seem to be proper, and they are showing as associated in the admin panel.

I also have a number of other configurable products with different number of options.

All configurable products are showing the associated products but they are only showing the first 4 of the associated products.

Is there a setting that I'm missing that limits/sets the number of the associated products that are displayed on the front end? Possibly a setting that indirectly affects this?

EDIT I tested the "limit/set" theory and it seems that even after disabling 2 of the associated products in the configurable product, the last 2 are not showing. I double checked all settings with the last 2 simple products and they are identical to the products that are visible on the front end.

Does someone out there know if there is some kind of "bug" with size options? For all my products, the XXL and XXXL will not show as options as of now.

Answer 1

After going through all the attribute selections the answer lies in STORES->ATTRIBUTES->PRODUCT

Apparently, using the default Size options was OK without a label per option. There was no label defined for the size options S,M,L,XL which apparently is OK (those options still showed up on the front end).

But adding my own options (XXL, XXXL) and not properly adding a label in the Attribute options area, stopped them from showing.

I went into the attribute (size) options area and added the appropriate labels to all attribute (size) options, and they showed up on the front end.

Answer 2

My solution was yes to Use in Search Results Layered Navigation and filling out Manage Options (Values of Your Attribute)

The site has been fine without but for some reason after update to Magento ver. 2.1.6 I had problems.

Also make super sure you never have duplicate URL's another issue

Answer 3

I have another type of issue. We were creating products by script in Magento 2 site. The problem was some times configurable products do not show all the available options.

Associated simple products was all correct they all were in stock ..etc.

After checking many threads I just save my configurable attribute and it started working correct. We did try many ways to search in code but it may be magento 2 issue of attribute configuration.
