Tinybee z offset

[Akhteh]

Hello friends, I have a problem, please help me I have a tinybee v1 board, I use Marlin 2.1.2.5 firmware, everything works fine, but my only problem is that no matter how much z offset I give during printing, it has no effect, but it is applied in the next print, not on that print. Please if anyone can help me
