I think that there is a different problem with swap.btc (and other high value tokens) in liquidity pool rewards. Because the daily amount earned is too small to be paid. So the APR based on actual daily returns paid (as measured by Tribaldex.com) is much less than the total pool APR.
I don't know if there is any mechanism in the pools for accumulating the miniscule amount due, but even if there is, it's very confusing.
Please note that this doesn't stop me from adding to the pool. But it is a minor concern.
