Sub page without any drop down menu to be appeared

I have my label’s website and I’m new to WordPress and all advanced technical website-creating programs… I have this my website by hiring someone to create it since 1.5 years ago BUT after I paid him completely and now one year was passed, so he rarely rarely replied me! And till now I wait for many many weeks, he still didn’t reply to me what I want to know (to go further my website construction till it is finished so that I can finally promote it to the mass)

My label’s website is https://www.slavaprods.com
You guys please go to check it.
You please click at DISTRIBUTION ——> Tapes
Then you see My Tape listing is long, and the listing is not finished yet I still have many tapes to add there BUT I can not add more (the system went error always after I tried adding more). Simply I think that’s because the rest of my Tape listing should be started in new page.. right?

So I really want to have —-> [like in your website https://www.wolftyr.com Sorry I take his as example] when I clicked at “Music” (after clicking it, there is no sub-page drop down menu appeared – That is what I want!) then below of his Music CD listing in this page “Music” (which still there are more CDs in page 2, 3, 4..) it appears :

Pages: 1 2 3 4 Next> Last ?.

Yes, I mean I want this same thing for my website’s “Tapes” page WITHOUT any drop down menu to be appeared.

Could anyone please teach me to do that? If you don’t have time to teach by typing long.. Maybe could you recommend to any link(s) that I can learn to do that? The simple/easy way as possibly… Too advanced I think I can’t.

I tried googling it myself but most of them are teaching like Adding sub page /child page BUT it will have a drop down menu appeared.. I don’t want that.

Could you please help recommending me anything?

Hope to hear from any helpers soon. Please… I would like to finish updating the whole my website this long new year weekend to finally promote about it.

Thanks in advance for your kind help!
