GPT's disappearing

Does anyone else have a problem of GPT's disappearing? i had a few saved in the sidebar that keep disappearing, sometimes you can find them again but sometimes you can't, i had a paranormal one go missing twice and i couldn't find it the second time, one for car problems disappeared a few times and i've noticed it's gone again, and now wolfram GPT is gone and i can't find it in explore GPTs, only a knock off called 'wolframm'

Anyone know what's going on? the wolfram GPT was the final straw because i relied on that for math, physics and chemistry help.
