IBTS temp continuing to rise in cooldown mode?

Recently I’ve noticed that my IBTS temp continues to rise in cooldown mode. I’m having to switch to shutdown mode to get the IBTS temp to go down. The bean temp sensor does seem to go down in cooldown mode. The first time I noticed this was because my Bullet, thankfully started to beep and error code.

Any ideas why this is happening?

I have never seen this issue before on a V2.
When switching to cooling mode the algorithm changes to calculate the drum wall temperature instead of the beans. This could make it look like the temp is rising. If it keeps rising after 30s there could be something wrong and I would then contact aillio support.
