A 1/4 wave monopole over perfect ground is supposed to be around 36 ohms but except for 10m, the OPs antenna is shortened by traps that also act as loading coils to shorten the antenna on lower bands. A short loaded 1/4 wave antenna over a good ground can be 15 ohms or less.
Most people have insufficient counterpoise under their trap antenna and it can show a really good 50 ohm match on a band where it should be less than 20 ohms.

You should have several dozens of radials in place to get that impedance anywhere near 36 ohms. Two radials is nowhere near enough. Consider using at least 8 to 16 evenly spaced radials. That might get you just below 50 ohms. I suggest using (or borrowing) a noise bridge or an antenna analyzer to get the straight scoop on what impedance you're seeing.
