Missing Footrpint data

I’ve been noticing a lot of gaps on the Footprints (I’m using an 18 tick range bar on YM), checked other assets and still the same. Reloaded history, tried on another laptop and it seems like a feed issue. I’m currently on Rithmic, but I tried checking on another broker’s CQG feed, they’re exactly the same, gaps and data too. I’ve tried a quick Google search and tried to set custom tick data to 1 and 0.5, no luck. Any feedback would be appreciated, thanks!
