Interestingly, on my trading platform I am seeing 450 share volume traded on LAAC and 550 on LAC (unless I'm reading it wrong). I wish posting photos worked here, but it looks like the price settled on was around $8.50 on LAC and high $8s on LAAC. 

I've posted the photo to my twitter account. You can have a look there: https://twitter.com/ElithXlithium/status/1708883389271494792

I'm guessing these are just temp tickers until the final ones are set up?
