When you click ok after doing a manual plate solve, it should add a sync point to eqmod. To verify this, at the top right side of the eqascom app, click the button with arrows on it to expand the menu. On the expanded menu you will see a section called "Alignment / Sync". In that section click on the button that looks like a sheet of lined paper.
This will open the sync list. Every time you perform a platesolve function you should see the sync point added to the list. The important bit is to make sure that the bottom "Append" tick option is the only one selected.
Ticking all the options would start to build and save a pointing model, which we don't want to do as it tends to have an adverse effect. Pointing models in my opinion only ever work if your are pier mounted and your mount is a high end mount using very high resolution / absolute encoders, which your mount isn't. I know this through personal experience on my EQ8.
