I've tried updating our mb group plugin to the latest version, 1.2.17 and Meta Box to 4.15.9 and I am experiencing the following issues:
1) Adding a new group, when the existing groups are collapsed, opens the existing groups. Then the existing groups do not open/close all of their fields making the collapse option useless and confusing.
2) The group title is now blank, rather than the title of one of the group's fields (works fine with 1.2.15 version)
3) There is a new 'Remove' group text link but it doesn't do anything.
4) The original red delete group button deletes the group without any confirmation, which I thought 1.2.17 was to have implemented.
Thanks for help on this.
