You're correct.
This is the set of aspherics that should be avoided:

Characterized by 62 degree apparent field and focal lengths of 23mm, 10mm, and 4mm. I bought this set a while ago on Ebay for a grand total of $20 and they are very much a "you get what you pay for" situation. 23mm has glare and contrast issues like crazy. 10mm does too, and a crooked field stop. It's also noticeably softer no-axis than any other 10mm eyepiece. The 4mm is a flat out joke. Chromatic aberration city.
Here is the set of Gold line eyepieces
> Recently I got a 10mm and 4mm eyepiece
This rings some alarm bells. Are they the Svbony 10mm and 4mm 62 degree aspheric eyepieces from this set?
If so, that's definitely one problem. If not, then there are also other potential issues.
I recommend reading this article. It explains all of the issues that you can face when trying to observe the planets, and what you can do to fix some of them.
Sadly, the two biggest hurdles when trying to view details on the planet are largely outside of our control: how stable the atmosphere is, and the maximum altitude the planets get above the horizon. If that max altitude is very low due to your latitude, then your only choice is to just wait for the planets to get higher in the sky as they move through their orbits. This can take a few years depending on where you live.
