welcome to Hello IOTA!
Invalid consistency means that the input of the bundle doesn’t match the output.
The bundle is basically broken, which could be caused by a bad connection between the wallet and the node or between the node and its neighbours.
Can you hit the Retry button in the wallet? Try to use the same node as before.
If that doesn’t work, change node and try again.
If that doesn’t work either, please head over to the #trinity-discussion channel on Discord and talk to Trinity's devs directly.
