From time to time I cross broken Variant values’ order. Other words, an instance on the design file has a different variant values’ order than the main component or even instance of it, tested directly in the library. 

• It’s not always the same component.
• It’s appearing at random.
• Problem appearing only on instances used in design file with added library
• Other, same way created components works fine (until randomizer decide it’s their time).
• Seems like some informations are lost during loading or publishing library.

Library file

Component → “Size” variant

Instance → “Size” variant

Design file (library attached)

Instance → “Size” variant
