First I would recommend you do not move the profiles from the epson installed location to the ColorSync folder. There is no need to do this, and in fact could cause problems.
Problems like this normally can be resolved with a thorough cleanup of the printing system on the mac.
Download the Epson uninstaller utility from Epson, and use it to uninstall all Epson printer drivers that are on your computer.
Optionally you may also want to use the search function in the finder to locate any folders containing the word Epson. to do this you have to instruct the search to also look in system folders which it will only do if you click the plus sign to add a criteria, then make sure system files are included. This may even require you to select the popup in the line created when you click the + symbol, select other check the box by "system files" which will then make it a choice in the popup. ( I don't remember if the current macOS includes system files in the popup choice. after typing Epson into the search box, wait a second and you should see a choice that says name matches Epson. Click on that so it is looking only in filenames and not looking inside of actual files. If there are any epson folders in your system folders you may want to delete them
Open printer preferences and right click in the window with the list of printers. you will see a choice called reset printing system. This will wipe all printing preferences from the mac. This will remove all custom paper sizes and macOS presets. They can get corrupted.
I then recommend a restart, then download and install the current driver.
This has solved issues for many. It might be worth a shot.
