A cursory glance at that report shows exports slightly higher than pre brexit, but the figures are on a different basis. Pre brexit we didn't actually have imports and exports to count but did have a reporting system for inter-state transfers of goods (intrastat). It's hard to say how accurate the reporting was and not everything was counted-low value consignments were excluded.
We now have actual imports and exports of goods to count.
The services figure is based on surveys, so has all the uncertainty that entails.
I can't quite see how things going to NI from mainland UK are treated or how stuff is counted going from NI over its land border.
As @welshbairn says, the biggest single increase is in fuel, which is hardly structural and quite unusual in that most countries don't have a domestic oil extraction industry to protect and fuel can go most places without tarrifs. Also the price has increased by way more than inflation so there will be a big price component to this increase. A 150% increase where the price has doubled is something like a 25% increase in volume.
Like employment or growth data, this stuff is useful for seeing long term trends but looking at changes month by month is trying to find a signal in noise.
One trend is that our trade balance deficit is still increasing.
Maybe in five years or so we could draw some useful conclusion about how brexit is going from the headline stats but not yet.
