Indent and unindent disabled

I am trying to create a subtask. However, indent and unindent are both disabled. I’m using version 3.2.3247

Please share the project file and point to the task you have issues with.

I have this same issue having either exported a project or extracted it from a larger one. Any solution?

SOLVED. For anyone else looking at this for the same issue: this happens when you order tasks by a column, like name or date etc. so it tab to its previous tasks looses meaning.
Push again on the arrow to reverse order and AGAIN to go back to default or manual order.

For the record, this is not the only case when indent actions are disabled. For instance, they may be disabled if indenting or unindenting creates a dependency loop.
