Induction Matrix does not work properly. When building a Mekanism Induction Matrix regardless of size or tier it will not store over 2.14GRF. The Dev has confirmed it is a bug within the Mekanism version 9.8.1. The issue was resolved in the update 9.8.2 for Mekanism.

1. Build any size Induction Matrix using "Induction Casing", "Induction Port", "Basic/Advanced/Elite/Ultimate Induction Cell" and "Basic/Advanced/Elite/Ultimate Induction Providers"
2. The GUI will never display over 2.14GRF storage

The issue can be fixed by simply updating the Mekanism mod to the 9.8.2 version.

updated in new beta out soon
