Tempest bell not building combo after upgrading quality

As per the title. For some reason, I couldn't build combo points on tempest bell (lvl 19) anymore after upgrading the quality. Tested with normal staff attack, tempest furry, all to no avail. Also tested removing all support gems, and also tried the gem that gave 40% chance added combo points. Nothing worked.

I recrafted Tempest bell and the new bell (with no quality) worked as per normal.

Hi, i have met the same problem with Tempest Bell, wish I could read your post before I enhance my Bell, hope to fix it soon
