Bug when purchasing tiers in the Season 1 Battle Pass

Whenever you purchase tiers in a particular path on the battle pass, you MUST make sure that you have that path activated. I had the Engineer (Deniable Ops) path activated while viewing tiers in the Recon (Rogue Operations) path. I went to purchase the last two tiers for Recon using Battle Coins, and it instead purchased the first two tiers of the Engineer path because that was the path that was activated at the time. I confirmed this is a problem by activating the Recon path and trying again, this time it worked as it should and the last two tiers were unlocked.

I was doing this after i received the 300 coins from purchasing BF Pro pass. This unlocks 20/22 tiers in the Recon path immediately and the 300 coins you receive can be used to purchase tier 21 and 22. The offical EA response to this issue was only that "all in game purchases are final". If that is the case, then all other paths should not be able to be view (or tiers able to be purchased) unless first activated.
