No minute bar for corresponding ticks

Bar data and an excerpt from the tick data that I get with the following requests:
https://data.alpaca.markets/v2/stocks/GME/bars?start=2022-01-10T05:00:00Z&end=2022-01-10T09:30:00Z&timeframe=1Min&feed=SIP

Why is there no minute bar data for some ticks?

All odd-lots in those two minutes.
