2 transaction in same address - Please help
The address you linked has received two payments, if you control the private keys for that address then you have nothing to worry about, those coins are in your control. 

Generally, it is not best practices to reuse an address, as it is very bad for your privacy (and, potentially the privacy of your customers). However, in terms of being able to spend the coins later, there is no technical issue with receiving more than one payment to an address. 

You should be able to spend the two UTXOs as normal.
