Unselectable Smite / Unsaved Defaults?

I'm attempting to report a bug on the selection of summoner spells after a match lobby was kicked back into the Looking For Match menu.

I experienced this issue in dynamic queue.

1. I was assigned jungle as a role and went to change one of my spells to smite
2. I selected Smite at the same time the match lobby dissolved in place of Heal from my previous match
3. I entered another match lobby where I was unable to reselect smite as my summoner's spell, every time I tried to change it heal remained chosen instead.
4. My doing this change happened late into the picks and the match started up before I thought to dodge the queue and try to fix the issue by restarting client or something

(The result was Skarner with flash and heal attempting to find a role) [Surprisingly, we won that match]

My first question:

1. Why does the re-entry of a new lobby only save your TALENTS and RUNES but not your SUMMONER'S SPELLS as the default for the next match?

My second question: 2) Why does SMITE not appear as the default summoner's spell in either the D or F slot when being assigned into the JUNGLER role? (Not permanently enforced in case player agreed role swapping in lobby happens).

I do not know how accurately this bug can be reproduced but please consider the two questions proposed and solutions if only saving the last picked SUMMONER'S SPELLS the same way the RUNES and MASTERIES are saved after each selection in lobby.

Thank you for your time,
