this morning two lines appeared in my wallet transactions list, but they're still immature after more than 700 confirmations. Destination adresses don't seem to be mine, and the addresses have a different format, beginning with letter "b". What are them?

I'm having the same problem.

I think it's because all these 'b' transcation was locked, for details, read some reply above, and you will see why, it's not a mistake or bug
Sorry I missed that in the first post - thanks for clarifying!
Quoting portion of OP's post here for others to reference as well:
for the following 5 months and every 2 years thereafter. All rewards over 192 Verus
are time locked to mature at a random block between 129,600 and 1,181,520
OK! So, the number next to immature must be the block that line will be released to the wallet.
