Relievers used as starters is part of the game and documented in the usage/limitations section of the manual.

Earlier this season we had some problems with how the status was being computed and reported to the game in some instances---but the situation you describe does not seem out of the ordinary.

Although relievers who start are better able to come back at times (depending on recovery and BFA max), this is to be expected as releivers are used to warming up often and coming back on short rest. In any case, they are limited to total innings both during the regular season and in the playoffs.
