Title information missing from either page

I realize IMDb has undergone some upgrades in time.   Perhaps why my TV show page has since shown layout errors, when it used to be a full page scroll.

One of the page errors I'm talking about:  https://www.imdb.com/title/tt3643900/episodes/?season=1&ref_=ttep  Only 5 episodes listed, when the page used to be full. 

This link -showing the full list under All Years, instead of separated by the seasons:  https://www.imdb.com/title/tt3643900/episodes/?year=2009&ref_=ttep

Totally messed up for months now, with no answers, when I worked hard like many, to properly update episodes. To honor credits toward the artists who contributed their time.  It never used to be like this in the older days, when you simply added a new title. Or submitted corrections for current ones, like status updates etc.   Not sure what IMDb is doing (owned by Amazon)   But agents and clients have reached out to me, asking about the sublink pages for info on the TV series.  Reporting this 'short fall'   I don't know what to tell them, as I don't govern the pages.   But it's ridiculous. 

This TV series page used to show all 36 listed episodes.  Now barely showing 20, if that.   So obviously a system status glitch or bug that has messed it around. 

Any feedback on this?
