Double spending while sending zcash

I transfered zcash to some address by command:
zcash-cli sendtoaddress “t1WP58ShXj3MS336SZb5eDXPsvezTz7pdk3” 0.01
=> 15d4eb3da3637bb26948cfdd1f70fc341f826a523ca90c891b510428222b8fff

to check transaction I used:
zcash-cli gettransaction 15d4eb3da3637bb26948cfdd1f70fc341f826a523ca90c891b510428222b8fff

}

However, block explorer shows that I sent 0.02. One address is what I wanted, but there is unknown t1JbhS2FuqC77yvZKgoTKoSgPvX162YgfJP popped up. Check https://explorer.zcha.in/transactions/15d4eb3da3637bb26948cfdd1f70fc341f826a523ca90c891b510428222b8fff
