In general I am of the view that you should make life as simple as possible for the immigration officer. I did not put my bachelor's degree information in education history - precisely because I felt putting partial information (no ECA nor a decent transcript) would be more detrimental than discarding it. Another point that I considered was that my bachelor's was more than 10 years in my past and did not show up in my personal history - so it would not be obvious in a cross check.
Also, for my spouse, I followed the same principle - just kept her Master's and removed her previous degrees. Being of a similar vintage, her bachelor studies were also completed well before the 10 year personal history.
@qaisahmed - I would say do what you deem best. People (including me) have anecdotal evidence of what worked - but whether they did the right thing or got lucky is up for debate
You are safe from a points perspective - so at the most you may face a bit of delay. Which in the scheme of things with IRCC is a possibility even if you have a perfect application
Good luck!
