There indeed seems to be a problem with the swap payment system. While I received my swaps at the regular time some of them looked a little too low in value. I'm not sure though as the past days have been quite turbulent with the spike to 0.3 and 0.18. A user on reddit has opened up a similar thread concerning this topic:

While I was sceptical at first I ultimately think he's not bullshitting although I don't believe BFX is intentionally scamming.

Like 20 minutes ago there was a second, very low swap credited on my account so it seems there actually is a problem. Please investigate at least the last 10 days, BFX and be open about it.
