Is there anything I should do to solve?

Can you email us the strategy XML file to support@wealth-lab.com?
I have a similar problem. After updating to build 29, I can no longer open some (not all) Building Block strategies correctly (an empty strategy appears).
On another PC with build 28 I can open the same strategy without problems.
On another PC with build 28 I can open the same strategy without problems.
I use the IBS indicator in the strategy. This has since build 29 obviously a new parameter. Maybe this causes the problem
Good catch, yes that’s right. Volker requested we add the period parameter so I think yes, any strategy that happened to use IBS in the short time since it’s debut will need to be re-created.
