Why is my lightning node performing RBF on-chain for a non-existent tx? (After force closing the channel with expired HTLC)

I am using lightning core and have a kill channel with active HTLC and funds were sent to myself at this address bc1qca5lwlfv8qzkchcfqdryfl89szuk2n0c3x2p7vt4gst04keygkns4x68hh (bc1qf7nh8pwt30nxueqekrhapa3wyz98zxu58rfl8l was used) and after expiry d HTLC (3 days later) funds were sent to the same address . Force quit (bc1qca5lwlfv8qzkchcfqdryfl89szuk2n0c3x2p7vt4gst04keygkns4x68hh).

Since then the funds have been stuck and I can’t find them in the logs doing the txid’s RBF onchain and I can see the fees keep increasing (I show two examples of log fees from 2728 to 14841).

I would appreciate it if someone could explain why my node is doing this.

thank you
