Bitcoin transaction IDs are consisted of 64 hexadecimal characters, without minus sign. An example:

These strings you've written aren't familiar.
I had this problem last year. I had to wait, I don't know, 3-4 months before they were dropped by the network.
This sounds strange. Unconfirmed transactions are commonly dropped by the nodes' mempool after 2 weeks by default, if they aren't included into a block until then. You must have meant something else.
