You might want to ask in the Discord and see what one of the mods say. I see that fire-born said you had a little over 10 SPT, but you say you have 4. Just thinking out loud, but if you have some up for sale, the Splinterlands airdrop page says this:

Please note that DEC or other game tokens listed for sale on external bid/ask markets (not liquidity pools) such as Steem Engine, Hive Engine, and TronTrade will not be eligible for the airdrop rewards.

I wonder about the spelling when you delegated, everyone uses lower-case, but you didn't in this post (it may not matter, just thinking). With only 4 SPT, I also wonder if there's a minimum number needed? But that's about all I can think of. Head on over to the Splinterlands Discord, and maybe they can help you more. Good luck!
