Legacy address is the original format of the Bitcoin network. Segwit address is the newer address format.
Although Bitcoin.com wallet may show legacy address instead of Segwit address under "Transaction History", both addresses will belong to the same receiver.
SegWit addresses start with 3 or bc1. Legacy addresses start with 1.
Segwit address reduces the size of the transaction that needs to be stored in one block. This allows the network to process more transactions per block.

To verify that the transaction was delivered to the same receiver, please visit these links and check for Hex string.
If the Hex string comes up as the same result that means both legacy and segwit address belongs to the same person and the BTC was delivered successfully.
