I have the same problem as you. It displays “IVALID ADDRESS” on the transaction ID, and if i click it, I get the invalid block message on the Raiblocks website.
I’ve sent a support ticket and i don’t have an answer still - maybe tomorrow. This should be easily fixable, since no coins have actually been sent; the only thing that changed was my xrb balance.
Let me know if the issue has been fixed.
