Welcome Mike!
Keep in mind that that West Coast Pale Ale is VERY OLD (in 2012 Mr. Beer was bought by Coopers and they discontinued all the old refills, including West Coast Pale Ale. So that can was at least 5 years old, and probably 3 or 4 years past the date on the can). Sitting in that can it has undergone what's called the maillard reaction, i.e. it's darken considerably. Some of it will also have become unfermentable, meaning your beer will end up sweeter than intended. Lastly, the yeast was probably years past viability, so while it may be fermenting, it's likely pretty stressed out. The good news is that it will still make beer, and every batch going forward will be better.
When you buy your next refills, I would strongly recommend immediately refrigerating the yeast packets which will dramatically improve their quality if you store them for a long time. You can safely use one 2 years past the date on the packet if you do that. If it's kept in a high heat environment, it cuts the viability very quickly.
After you get this batch out of the way, for BAA I'd recommend 3 weeks fermenting, and keep the temp of the wort during fermentation in the high 60s at most. Then 4 weeks in the bottle at 70 or above. BAA is one of the better Mr. Beer refills.
