Having only one region in toml caused issue

[jennieli421]

I wanted to perform a run with only enrichment, so I had one region specified in TOML like the following. But I did not see any unblock actions from the live state panel. The purple peak indicating voltage reversals did not appear at all in the histogram. However, everything works fine as long as I add a region with control=true. I also tried with two regions with control=false and that also didn't have any rejection.

n_threads = 8

[[regions]]
name = "analysis"
control = false
min_chunks = 1 # minimum number of chunks before a decision can be made
max_chunks = 1 # maximum number of chunks to use in decision making - after this perform the above_max_chunks action
targets = []  # Genomic targets for this region
single_on = "unblock"
multi_on = "unblock"
single_off = "stop_receiving"
multi_off = "stop_receiving"
no_map = "proceed"
no_seq = "proceed"
above_max_chunks = "unblock"  # Action to take if the number of chunks received is above max_chunks
below_min_chunks = "proceed"  # Action to take if the number of chunks received is below min_chunks
