Getblockchaininfo showing "segwit":{ status: "failed"

Getblockchaininfo showing "segwit":{ status: "failed"

I have created a clone of Bitcoin for educational purposes. The network seems to be running, I changed prefixes, ports and other parameters and everything seemed fine. However, most (but not all) sent transactions sit in the mempool and do not actually get into the blockchain. I think it may be because of the version of the node. Here is what I get when I use getblockchaininfo (I believe it is related to the problem of nodes ignoring transactions in mempools). Can you please help figure this out?
